Trait CliContext

Required Methods

fn with_prefix<'b>( &'b mut self, prefix: &str, ) -> Option<PrefixedExecutor<'a, 'b>>

Creates a new prefixed execution context, but only if the current line matches. Reduces the processing overhead for large tree command environments.

fn command<'b>(&'b mut self, cmd: &str) -> Option<CommandContext<'b>>

Announces a command to be executed. Returns an execution context in case the command is invoked.

fn property<'b, V, P, Id: Into<Cow<'b, str>>>( &'b mut self, property_id: Id, input_parser: P, ) -> Option<PropertyContext<'b, V>>

where P: ValueInput<V>, V: Display,

Announces a property that can be manipulated. Returns an execution context in case the property is to be either retrieved or updated.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
