Enum AuthScheme 

pub enum AuthScheme {
    Auto,
    PrivateToken,
    Bearer,
}

How to send the token to GitLab.

GitLab self-hosted accepts two distinct auth headers depending on token type:

• PRIVATE-TOKEN — Personal Access Tokens (glpat-*), OAuth Application Secrets used as PAT (gloas-*), Deploy Tokens (gldt-*), Runner Authentication Tokens (glrt-*).
• Authorization: Bearer — OAuth access_tokens issued by the /oauth/token Doorkeeper endpoint (no documented prefix).

Sending an OAuth access_token via PRIVATE-TOKEN returns 401 Unauthorized; sending a PAT via Authorization: Bearer works against gitlab.com but is rejected by some self-hosted setups. AuthScheme::Auto keeps the historical behaviour of detecting the scheme by the well-known prefix; PrivateToken / Bearer let the caller force the choice when they already know the token’s origin.

Variants

Auto

Detect by token prefix (default — backward compatible).

PrivateToken

Force PRIVATE-TOKEN: <token>.

Bearer

Force Authorization: Bearer <token>.

Trait Implementations

impl Clone for AuthScheme

fn clone(&self) -> AuthScheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AuthScheme

impl Debug for AuthScheme

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

Formats the value using the given formatter.

impl Default for AuthScheme

fn default() -> AuthScheme

Returns the “default value” for a type.

impl Eq for AuthScheme

impl PartialEq for AuthScheme

fn eq(&self, other: &AuthScheme) -> 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.
