Function eql [src]

Returns true if and only if the slices have the same length and all elements compare true using equality operator.

Prototype

pub fn eql(comptime T: type, a: []const T, b: []const T) bool

Parameters

T: typea: []const Tb: []const T

Example

 test eql {
    try testing.expect(eql(u8, "abcd", "abcd"));
    try testing.expect(!eql(u8, "abcdef", "abZdef"));
    try testing.expect(!eql(u8, "abcdefg", "abcdef"));

    comptime {
        try testing.expect(eql(type, &.{ bool, f32 }, &.{ bool, f32 }));
        try testing.expect(!eql(type, &.{ bool, f32 }, &.{ f32, bool }));
        try testing.expect(!eql(type, &.{ bool, f32 }, &.{bool}));

        try testing.expect(eql(comptime_int, &.{ 1, 2, 3 }, &.{ 1, 2, 3 }));
        try testing.expect(!eql(comptime_int, &.{ 1, 2, 3 }, &.{ 3, 2, 1 }));
        try testing.expect(!eql(comptime_int, &.{1}, &.{ 1, 2 }));
    }

    try testing.expect(eql(void, &.{ {}, {} }, &.{ {}, {} }));
    try testing.expect(!eql(void, &.{{}}, &.{ {}, {} }));
}
