Struct RustExpr 

pub struct RustExpr(/* private fields */);

Rust expression syntax stored as static metadata.

Implementations

impl RustExpr

pub fn new(value: &'static str) -> Result<Self, RustSyntaxError>

Validates Rust expression syntax stored as static metadata.

Errors

Returns RustSyntaxError when value is not valid Rust expression syntax.

pub const fn from_macro_tokens_unchecked(value: &'static str) -> Self

Stores Rust expression syntax emitted by a trusted macro expansion.

pub const fn as_str(self) -> &'static str

Returns the stored Rust expression syntax.

pub fn parse(self) -> Result<Expr, RustSyntaxError>

Parses the stored Rust expression syntax.

Errors

Returns RustSyntaxError when the stored string is not valid Rust expression syntax.
