Function parse [src]

Converts UTF-8 text to a BuildId.

Prototype

pub fn parse(text: []const u8) !BuildId

Parameters

text: []const u8

Example

 test parse {
    try std.testing.expectEqual(BuildId.md5, try parse("md5"));
    try std.testing.expectEqual(BuildId.none, try parse("none"));
    try std.testing.expectEqual(BuildId.fast, try parse("fast"));
    try std.testing.expectEqual(BuildId.uuid, try parse("uuid"));
    try std.testing.expectEqual(BuildId.sha1, try parse("sha1"));
    try std.testing.expectEqual(BuildId.sha1, try parse("tree"));

    try std.testing.expect(BuildId.initHexString("").eql(try parse("0x")));
    try std.testing.expect(BuildId.initHexString("\x12\x34\x56").eql(try parse("0x123456")));
    try std.testing.expectError(error.InvalidLength, parse("0x12-34"));
    try std.testing.expectError(error.InvalidCharacter, parse("0xfoobbb"));
    try std.testing.expectError(error.InvalidBuildIdStyle, parse("yaddaxxx"));
}
