# Struct proc_macro::Term[−][src]

    pub struct Term { /* fields omitted */ }

🔬 This is a nightly-only experimental API. (`proc_macro` #38356)

An interned string.

## Methods

###

`impl Term`

[src]

####

`pub fn new(string: &str, span: Span) -> Term`

[src]

🔬 This is a nightly-only experimental API. (`proc_macro` #38356)

Creates a new `Term` with the given `string` as well as the specified `span`.

Note that `span`, currently in rustc, configures the hygiene information for this identifier. As of this time `Span::call_site()` explicitly opts-in to non-hygienic information (aka copy/pasted code) while spans like `Span::def_site()` will opt-in to hygienic information, meaning that code at the call site of the macro can't access this identifier.

Due to the current importance of hygiene this constructor, unlike other tokens, requires a `Span` to be specified at construction.

####

`pub fn as_str(&self) -> &str`

[src]

🔬 This is a nightly-only experimental API. (`proc_macro` #38356)

Get a reference to the interned string.

####

`pub fn span(&self) -> Span`

[src]

🔬 This is a nightly-only experimental API. (`proc_macro` #38356)

Returns the span of this `Term`, encompassing the entire string returned by `as_str`.

####

`pub fn set_span(&mut self, span: Span)`

[src]

🔬 This is a nightly-only experimental API. (`proc_macro` #38356)

Configures the span of this `Term`, possibly changing hygiene information.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
