Struct AuthConfig 

pub struct AuthConfig { /* private fields */ }

Loaded bearer-token validator. Constructed once at startup; cloneable across handlers via Arc<AuthConfig>.

Implementations

impl AuthConfig

pub fn from_file(path: &Path) -> Result<Self>

Load tokens from a file. One token per line; blank lines and lines starting with # are ignored. Trailing whitespace is trimmed from each token. Returns an error if the file is empty after parsing.

pub fn from_inline(token: &str) -> Result<Self>

Build from a single inline token. The caller is expected to have already trimmed; we trim defensively to catch obvious mistakes.

pub fn token_count(&self) -> usize

Number of distinct tokens loaded. For startup logging only — never log the tokens themselves.

pub fn validate(&self, presented: &[u8]) -> bool

Validate a presented token in constant time relative to the length of the candidate set. Returns true iff the presented token byte- equals one of the loaded tokens.

The comparison is constant-time per candidate (no early exit on first mismatching byte); the loop over candidates is linear, which is fine because the operator controls the candidate count and it is small (typically 1–10). An attacker cannot insert candidates, so the linear scan does not leak exploitable timing information.

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

Formats the value using the given formatter.
