Struct actix_web_location::providers::FallbackProvider

source · [−]

pub struct FallbackProvider { /* private fields */ }

Expand description

A “dummy” provider that returns None for all fields.

Implementations

source

impl FallbackProvider

source

pub fn new(fallback_builder: LocationBuilder) -> Self

Create a fallback provider.

The passed location builder will be modified to include the provider name.

Trait Implementations

source

impl Provider for FallbackProvider

source

fn name(&self) -> &str

Provide a name of the provider for use in diagnostics.

source

fn get_location<'life0, 'life1, 'async_trait>(
 &'life0 self,
 _request: &'life1 HttpRequest
) -> Pin<Box<dyn Future<Output = Result<Option<Location>, Error>> + 'async_trait>> where
 'life0: 'async_trait,
 'life1: 'async_trait,
 Self: 'async_trait,

Derive a location from a request’s metadata.

source

fn expect_country(&self) -> bool

Can this provider produce locations with country information?

source

fn expect_region(&self) -> bool

Can this provider produce locations with region information?

source

fn expect_city(&self) -> bool

Can this provider produce locations with city information?
