Struct Engine 

pub struct Engine<'a> {
    pub name: Option<Cow<'a, str>>,
    pub major: Option<Cow<'a, str>>,
    pub minor: Option<Cow<'a, str>>,
    pub patch: Option<Cow<'a, str>>,
}

The layout engine of the product a user agent belongs to.

Fields

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

The engine name, or None when no pattern matches.

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

The major version, if the matching pattern captures one.

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

The minor version, if the matching pattern captures one.

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

The patch version, if the matching pattern captures one.

Implementations

impl<'a> Engine<'a>

pub fn version(&self) -> Option<Cow<'_, str>>

Joins the version parts into a full version string, stopping at the first part which is missing.

use std::borrow::Cow;

use user_agent_parser::Engine;

let engine = Engine {
    name:  Some(Cow::from("Blink")),
    major: Some(Cow::from("57")),
    minor: Some(Cow::from("0")),
    patch: Some(Cow::from("2987")),
};

assert_eq!(Some(Cow::from("57.0.2987")), engine.version());

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

Extracts the owned data.

Trait Implementations

impl<'a> Clone for Engine<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Engine<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Engine<'a>

fn default() -> Engine<'a>

Returns the “default value” for a type.

impl<'a> Eq for Engine<'a>

impl<'r> FromRequest<'r> for Engine<'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 &Engine<'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 Engine<'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 Engine<'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 Engine<'a>

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

Equality operator ==.

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

Inequality operator !=.

impl<'a> StructuralPartialEq for Engine<'a>
