Enum ContextItem 

pub enum ContextItem {
    Command(CommandItem),
    Environment(EnvironmentItem),
    DelimiterControl(DelimiterControlItem),
}

A runtime-injectable definition that augments the knowledge base.

Context items let callers add temporary commands, environments, or delimiter controls without modifying the underlying package specs.

Variants

Command(CommandItem)

A command definition (prefix, infix, or declarative)

Environment(EnvironmentItem)

An environment definition

DelimiterControl(DelimiterControlItem)

A delimiter control sequence (e.g. langle, rangle)

Implementations

impl ContextItem

pub fn name(&self) -> &str

Return the name of the underlying item (command name, env name, etc.)

pub const fn target_tag(&self) -> &'static str

Human-readable tag for error messages ("command", "environment", etc.)

Trait Implementations

impl Clone for ContextItem

fn clone(&self) -> ContextItem

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ContextItem

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

Formats the value using the given formatter.

impl Eq for ContextItem

impl From<CommandItem> for ContextItem

fn from(item: CommandItem) -> Self

Converts to this type from the input type.

impl From<DelimiterControlItem> for ContextItem

fn from(item: DelimiterControlItem) -> Self

Converts to this type from the input type.

impl From<EnvironmentItem> for ContextItem

fn from(item: EnvironmentItem) -> Self

Converts to this type from the input type.

impl PartialEq for ContextItem

fn eq(&self, other: &ContextItem) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
