Trait syn::synom::Parser
[−]
[src]
pub trait Parser: Sized { type Output; fn parse2(self, tokens: TokenStream) -> Result<Self::Output, ParseError>; fn parse(self, tokens: TokenStream) -> Result<Self::Output, ParseError> { ... } fn parse_str(self, s: &str) -> Result<Self::Output, ParseError> { ... } }
Parser that can parse Rust tokens into a particular syntax tree node.
Refer to the module documentation for details about parsing in Syn.
This trait is available if Syn is built with the "parsing"
feature.
Associated Types
type Output
Required Methods
fn parse2(self, tokens: TokenStream) -> Result<Self::Output, ParseError>
Parse a proc-macro2 token stream into the chosen syntax tree node.
Provided Methods
fn parse(self, tokens: TokenStream) -> Result<Self::Output, ParseError>
Parse tokens of source code into the chosen syntax tree node.
This method is available if Syn is built with both the "parsing"
and
"proc-macro"
features.
fn parse_str(self, s: &str) -> Result<Self::Output, ParseError>
Parse a string of Rust code into the chosen syntax tree node.
Hygiene
Every span in the resulting syntax tree will be set to resolve at the macro call site.
