Struct tvix_cli::assignment::Assignment

pub(crate) struct Assignment<'a> {
    pub(crate) ident: &'a str,
    pub(crate) value: Expr,
}

An assignment of an identifier to a value in the context of a REPL.

Fields

ident: &'a str

value: Expr

Implementations

impl<'a> Assignment<'a>

pub fn parse(input: &'a str) -> Option<Self>

Try to parse an Assignment from the given input string.

Returns None if the parsing fails for any reason, since the intent is for us to fall-back to trying to parse the input as a regular expression or other REPL commands for any reason, since the intent is for us to fall-back to trying to parse the input as a regular expression or other REPL command.

Trait Implementations

impl<'a> Clone for Assignment<'a>

fn clone(&self) -> Assignment<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Assignment<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Assignment<'a>

fn eq(&self, other: &Assignment<'a>) -> 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.
