pub struct Backend { /* private fields */ }
Expand description
A named backend.
This represents a backend associated with a service that we can send requests to, potentially caching the responses received.
Implementations
sourceimpl Backend
impl Backend
sourcepub fn from_name(s: &str) -> Result<Self, BackendError>
pub fn from_name(s: &str) -> Result<Self, BackendError>
Get a backend by its name.
This function will return a BackendError
if an invalid name was given.
Backend names:
- cannot be empty
- cannot be longer than 255 characters
- cannot ASCII control characters such as
'\n'
orDELETE
. - cannot contain special Unicode characters
- should only contain visible ASCII characters or spaces
Future versions of this function may return an error if your service does not have a backend with this name.
sourcepub fn into_string(self) -> String
pub fn into_string(self) -> String
Turn the backend into its name as a string.
