Struct darling::util::IdentString

[+] Show declaration

pub struct IdentString { /* fields omitted */ }

[−] Expand description

A wrapper for an Ident which also keeps the value as a string.

This struct can be used to perform string comparisons and operations.

Implementations

impl IdentString[−]

pub fn new(ident: Ident) -> IdentString[−]

Create a new IdentString.

pub fn as_ident(&self) -> &Ident[−]

Get the ident as a proc_macro2::Ident.

pub fn as_str(&self) -> &str[−]

Get the ident as a string.

pub fn span(&self) -> Span[−]

Get the location of this Ident in source.

pub fn map<F, S>(self, map_fn: F) -> IdentString where
    F: FnOnce(String) -> S,
    S: AsRef<str>, [−]

Apply some transform to the ident’s string representation.

Panics

This will panic if the transform produces an invalid ident.
