Implementations§

Source§

impl Context

Source

pub const fn global(&self) -> &GlobalContext

Global context

Source

pub const fn group(&self) -> &GroupContext

Group context, is equal to GlobalContext if the call is from the global scope.

Source

pub const fn buffer_len(&self) -> usize

Returns the length in bytes of the output buffer. This is the maximum size of the data that can be returned by the extension.

Source

pub fn callback_data<V>( &self, name: &str, func: &str, data: V, ) -> Result<(), CallbackError>
where V: IntoArma,

Source

pub fn callback_null(&self, name: &str, func: &str) -> Result<(), CallbackError>
