Implementations

impl JsonConfig

pub fn limit(self, limit: usize) -> Self

Change max size of payload.

By default max size is 32Kb

pub fn content_type<F>(self, predicate: F) -> Self

where F: Fn(Mime) -> bool + Send + Sync + 'static,

Set predicate for allowed content types.

JSON content types (*/json and */*+json) are always accepted. The predicate can accept additional types.

Performs copy-assignment from source.

impl Debug for JsonConfig

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

Formats the value using the given formatter.

impl Default for JsonConfig

fn default() -> Self
