ContextPool

Struct ContextPool 

Source
pub struct ContextPool { /* private fields */ }
Expand description

A pool of proto contexts.

Makes using multiple contexts easy, by caching contexts by protocol type and initializing them on demand.

Implementations§

Source§

impl ContextPool

Source

pub fn empty() -> Self

Create new empty pool.

Source

pub fn get_mut<'a>(&'a mut self, config: &'a Config) -> Result<&'a mut Context>

Get mutable context for given proto.

This will initialize the context if no context is loaded for the given proto yet. This may error..
