Function replaceOwned [src]

Perform a replacement on an allocated buffer of pre-determined size. Caller must free returned memory.

Prototype

 pub fn replaceOwned(comptime T: type, allocator: Allocator, input: []const T, needle: []const T, replacement: []const T) Allocator.Error![]T

Parameters

T: typeallocator: Allocatorinput: []const Tneedle: []const Treplacement: []const T

Example

 test replaceOwned {
    const gpa = std.testing.allocator;

    const base_replace = replaceOwned(u8, gpa, "All your base are belong to us", "base", "Zig") catch @panic("out of memory");
    defer gpa.free(base_replace);
    try testing.expect(eql(u8, base_replace, "All your Zig are belong to us"));

    const zen_replace = replaceOwned(u8, gpa, "Favor reading code over writing code.", " code", "") catch @panic("out of memory");
    defer gpa.free(zen_replace);
    try testing.expect(eql(u8, zen_replace, "Favor reading over writing."));
}
