Struct EngineKey 

pub struct EngineKey {
    pub engine: VendorId,
    pub version: Option<String>,
    pub target_class: TargetClass,
    pub tls_profile: Option<String>,
}

Durable identity of a scraping target’s anti-bot engine.

Two EngineKey values are equal iff every field is equal — including the optional version and tls_profile. This is deliberate: an Akamai Bot Manager v3 patch must not silently apply to a v4 deployment, and a Chrome-136 TLS-profile patch must not silently apply to a Firefox-130 profile.

The field layout matches the T110 spec: engine is the anti-bot engine family, version is the vendor’s revision (e.g. bot-manager-v3), target_class is the site’s posture, and tls_profile is the client-side TLS fingerprint (e.g. chrome136).

Example

use stygian_charon::challenge_feedback::EngineKey;
use stygian_charon::types::TargetClass;
use stygian_charon::vendor_classifier::VendorId;

let key = EngineKey {
    engine: VendorId::Cloudflare,
    version: Some("bot-manager-v3".to_string()),
    target_class: TargetClass::Api,
    tls_profile: Some("chrome136".to_string()),
};
assert_eq!(key.engine, VendorId::Cloudflare);
assert_eq!(key.version.as_deref(), Some("bot-manager-v3"));

Fields

engine: VendorId

Anti-bot engine family. Use VendorId::Unknown only when no engine could be classified.

version: Option<String>

Optional vendor version (e.g. "bot-manager-v3"). None means the version is unknown or unversioned.

target_class: TargetClass

Target class (api / content_site / high_security / unknown).

tls_profile: Option<String>

Optional client TLS profile (e.g. "chrome136"). None means the TLS profile was not recorded.

Implementations

impl EngineKey

pub const fn engine_label(&self) -> &'static str

Engine component of the key, used for display and stable hashing. Returns VendorId::label.

pub fn validate(&self) -> Result<(), EngineKeyParseError>

Validate the key has no empty optional fields. Returns Ok(()) for well-formed keys; otherwise a EngineKeyParseError::EmptyModifier.

This is primarily a helper for FromStr but is also useful when constructing keys from user-supplied config.

Errors

Returns EngineKeyParseError::EmptyModifier if either optional component is an empty string.

Trait Implementations

impl Clone for EngineKey

fn clone(&self) -> EngineKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EngineKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for EngineKey

fn default() -> EngineKey

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EngineKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EngineKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for EngineKey

impl FromStr for EngineKey

type Err = EngineKeyParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for EngineKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for EngineKey

fn cmp(&self, other: &EngineKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for EngineKey

fn eq(&self, other: &EngineKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for EngineKey

fn partial_cmp(&self, other: &EngineKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for EngineKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
