Function protox_parse::parse

pub fn parse(source: &str) -> Result<FileDescriptorProto, ParseError>

Parses a single protobuf source file into a FileDescriptorProto.

This function only looks at the syntax of the file, without resolving type names or reading imported files.

Examples

let source = r#"
    syntax = "proto3";
    import "dep.proto";

    message Foo {
        Bar bar = 1;
    }
"#;
let file_descriptor = parse(source).unwrap();
assert_eq!(file_descriptor, FileDescriptorProto {
    syntax: Some("proto3".to_owned()),
    dependency: vec!["dep.proto".to_owned()],
    message_type: vec![DescriptorProto {
        name: Some("Foo".to_owned()),
        field: vec![FieldDescriptorProto {
            label: Some(Label::Optional as _),
            name: Some("bar".to_owned()),
            number: Some(1),
            type_name: Some("Bar".to_owned()),
            json_name: Some("bar".to_owned()),
            ..Default::default()
        }],
        ..Default::default()
    }],
    source_code_info: Some(SourceCodeInfo {
        /* ... */
    }),
    ..Default::default()
})
