}

Function argument pattern in Nix.

Variants

Ident(String)

Simple identifier pattern: x: body

AttrPattern

Attribute set pattern: { a, b, c ? default, ... }: body

Fields

attrs: Vec<(String, Option<NixExpr>)>

Named attributes to destructure, with optional defaults

ellipsis: bool

Whether ... (ellipsis) is present to allow extra attributes

AtPattern

At-pattern combining set destructuring with a binding: { a, b } @ pkg: body (or pkg @ { a, b }: body)

Fields

ident: String

The identifier binding for the whole set

ident_first: bool

Whether the ident comes before or after the @

attrs: Vec<(String, Option<NixExpr>)>

Set pattern attributes

ellipsis: bool

Whether ... is present

Trait Implementations

impl Clone for NixPattern

fn clone(&self) -> NixPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NixPattern

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

Formats the value using the given formatter.

impl PartialEq for NixPattern

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