Struct yash_syntax::syntax::Switch

source · [−]

pub struct Switch {
    pub type: SwitchType,
    pub condition: SwitchCondition,
    pub word: Word,
}

Expand description

Parameter expansion modifier that conditionally substitutes the value being expanded.

Examples of switches include +foo, :-bar and :=baz.

A switch is composed of a condition (an optional :), a type (one of +, -, = and ?) and a word.

Fields

type: SwitchType

How the value is substituted.

condition: SwitchCondition

Condition that determines whether the value is substituted or not.

word: Word

Word that substitutes the parameter value.
