    pub value: Value,
    pub location: Location,
}

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

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

Converts a string to an assignment.

Returns Err(None) if the string is not an assignment word.

type Err = Option<Error>

The associated error which can be returned from parsing.

impl PartialEq<Assign> 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: &Assign) -> bool

This method tests for !=.

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.
