Struct UserAgent 

pub struct UserAgent<'a> {
    pub user_agent: Option<Cow<'a, str>>,
}

Available on crate features axum or rocket only.

The raw User-Agent header of a request.

Fields

user_agent: Option<Cow<'a, str>>

The header value, or None when the request carries no User-Agent header.

Implementations

impl<'a> UserAgent<'a>

pub fn into_owned(self) -> UserAgent<'static>

Extracts the owned data.

Trait Implementations

impl<'a> Clone for UserAgent<'a>

fn clone(&self) -> UserAgent<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for UserAgent<'a>

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

Formats the value using the given formatter.

impl<'a> Default for UserAgent<'a>

fn default() -> UserAgent<'a>

Returns the “default value” for a type.

impl<'a> Eq for UserAgent<'a>

impl<'r> FromRequest<'r> for UserAgent<'r>

Available on crate feature rocket only.

type Error = ()

The associated error to be returned if derivation fails.

fn from_request<'life0, 'async_trait>( request: &'r Request<'life0>, ) -> Pin<Box<dyn Future<Output = OutcomeResult<Self, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'r: 'async_trait, 'life0: 'async_trait,

Derives an instance of Self from the incoming request metadata.

impl<'r> FromRequest<'r> for &UserAgent<'r>

Available on crate feature rocket only.

type Error = ()

The associated error to be returned if derivation fails.

fn from_request<'life0, 'async_trait>( request: &'r Request<'life0>, ) -> Pin<Box<dyn Future<Output = OutcomeResult<Self, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'r: 'async_trait, 'life0: 'async_trait,

Derives an instance of Self from the incoming request metadata.

impl<S: Send + Sync> FromRequestParts<S> for UserAgent<'static>

Available on crate feature axum only.

type Rejection = Infallible

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

async fn from_request_parts( parts: &mut Parts, _state: &S, ) -> Result<Self, Self::Rejection>

Perform the extraction.

impl<'a> Hash for UserAgent<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for UserAgent<'a>

fn eq(&self, other: &UserAgent<'a>) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
