Struct yash_syntax::syntax::Assign

pub struct Assign {
    pub name: String,
    pub value: Value,
    pub location: Location,
}

Assignment word.

Fields

name: String

Name of the variable to assign to.

In the valid assignment syntax, the name must not be empty.

value: Value

Value assigned to the variable.

location: Location

Location of the assignment word.

Trait Implementations

impl Clone for Assign

fn clone(&self) -> Assign

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Assign

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

Formats the value using the given formatter.

impl Display for Assign

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

Formats the value using the given formatter.

impl FromStr for Assign

Converts a string to an assignment.

type Err = Option<Error>

Optional error value

The error is None if the input is a valid word but not an assignment. A proper error is returned in Some(_) in case of a syntax error.

fn from_str(s: &str) -> Result<Assign, Option<Error>>

Parses a string s to return a value of this type.

impl PartialEq for Assign

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<Word> for Assign

Fallible conversion from a word into an assignment.

fn try_from(word: Word) -> Result<Assign, Word>

Converts a word into an assignment.

For a successful conversion, the word must be of the form name=value, where name is a non-empty literal word, = is an unquoted equal sign, and value is a word. If the input word does not match this syntax, it is returned intact in Err.

type Error = Word

The type returned in the event of a conversion error.
