Enum PkceMethod 

pub enum PkceMethod {
    S256,
    Plain,
}

PKCE code challenge method.

Deliberately not #[non_exhaustive]: a new method from a future spec is a semver event we want to make deliberately.

Variants

S256

S256 — base64url(SHA256(code_verifier)). The only method OAuth 2.1 permits.

Plain

plain — the verifier is sent as the challenge. Forbidden by OAuth 2.1 §7.5.2; see the module docs.

Implementations

impl PkceMethod

pub fn as_str(self) -> &'static str

The method’s code_challenge_method wire value.

pub fn parse(value: &str) -> Result<Self, PkceError>

Parse a code_challenge_method value.

The comparison is exact: RFC 7636 registers plain and S256, and these values are compared byte-for-byte, so a near-miss is an error rather than a mismatch.
