Struct rune::ast::File

pub struct File {
    pub attributes: Vec<Attribute>,
    pub items: Vec<(Item, Option<SemiColon>)>,
}

items: Vec<(Item, Option<SemiColon>)>

All the declarations in a file.

Trait Implementations

impl Clone for File

fn clone(&self) -> File

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for File

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

Formats the value using the given formatter.

impl Eq for File

impl OptionSpanned for File

fn option_span(&self) -> Option<Span>

impl Parse for File

Parse a file.

Examples

use rune::{testing, ast};

testing::roundtrip::<ast::File>(r#"
use foo;

fn foo() {
    42
}

use bar;

fn bar(a, b) {
    a
}
"#);

Realistic Example

use rune::{testing, ast};

testing::roundtrip::<ast::File>(r#"
use http;

fn main() {
    let client = http::client();
    let response = client.get("https://google.com");
    let text = response.text();
}
"#);

File Attributes Example

use rune::{testing, ast};

testing::roundtrip::<ast::File>(r#"
// NB: Attributes are currently rejected by the compiler
#![feature(attributes)]

fn main() {
    for x in [1,2,3,4,5,6] {
        println(`{x}`)
    }
}
"#);

fn parse(p: &mut Parser<'_>) -> Result<Self, ParseError>

Parse the current item from the parser.

impl PartialEq<File> for File

fn eq(&self, other: &File) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &File) -> bool

This method tests for !=.

impl StructuralEq for File

impl StructuralPartialEq for File

impl ToTokens for File

fn to_tokens(&self, context: &MacroContext, stream: &mut TokenStream)

Turn the current item into tokens.
