Function parse_vendor_definition 

pub fn parse_vendor_definition(
    toml_text: &str,
) -> Result<VendorDefinition, VendorError>

Parse a raw TOML payload into a VendorDefinition.

The TOML is expected to declare the id field as the lower-case VendorId label (e.g. "datadome"). The loader maps that label into a VendorId discriminant and rejects unknown ids with VendorError::UnknownVendorId.

Errors

Returns VendorError when the TOML fails to parse, the declared id is not part of the supported taxonomy, or the resulting VendorDefinition fails validate.
