Struct Directive 

pub struct Directive {
    pub name: String,
    pub arguments: Vec<Arg>,
}

Represent a directive invocation. This combines a directive name (or abbreviation) with the list of actual arguments provided. See [Self.execute()] to actually perform this directive’s action.

Fields

name: String

The directive name.

arguments: Vec<Arg>

The directive arguments.

Implementations

impl Directive

pub fn execute(&self, config: &mut HhhArgs) -> Option<String>

Try to execute the directive. This performs lookup of the directive, where the name is allowed to be an (unambiguous) abbreviation of the directive name.

The return value is None on success and an error message on error.

Trait Implementations

impl Debug for Directive

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

Formats the value using the given formatter.

impl Default for Directive

fn default() -> Directive

Returns the “default value” for a type.

impl PartialEq for Directive

fn eq(&self, other: &Directive) -> 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.
