Struct LocalDecoder 

pub struct LocalDecoder { /* private fields */ }

JWT decoder that validates tokens using locally stored keys.

Supports multiple decoding keys and tries them sequentially until one succeeds. Ideal for scenarios with key rotation or multiple valid signing keys.

Example

use axum_jwt_auth::LocalDecoder;
use jsonwebtoken::{DecodingKey, Algorithm, Validation};

let keys = vec![DecodingKey::from_secret(b"secret")];
let mut validation = Validation::new(Algorithm::HS256);
validation.set_audience(&["my-app"]);

let decoder = LocalDecoder::builder()
    .keys(keys)
    .validation(validation)
    .build()
    .unwrap();

Implementations

impl LocalDecoder

pub fn new( keys: Vec<DecodingKey>, validation: Validation, ) -> Result<Self, Error>

Creates a new LocalDecoder with the specified keys and validation settings.

Errors

Returns Error::Configuration if:

• No decoding keys are provided
• No validation algorithms are configured
• No audience is specified in validation

pub fn builder() -> LocalDecoderBuilder

Creates a new LocalDecoderBuilder for configuring a decoder.

Trait Implementations

impl Clone for LocalDecoder

fn clone(&self) -> LocalDecoder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> JwtDecoder<T> for LocalDecoder

where T: for<'de> DeserializeOwned,

fn decode<'a>( &'a self, token: &'a str, ) -> Pin<Box<dyn Future<Output = Result<TokenData<T>, Error>> + Send + 'a>>

Decodes and validates a JWT token string, returning the parsed claims.
