Function valueAlloc [src]

Calls value and stores the result in dynamically allocated memory instead of taking a writer. Caller owns returned memory.

Prototype

pub fn valueAlloc(gpa: Allocator, v: anytype, options: Options) error{OutOfMemory}![]u8

Parameters

gpa: Allocatoroptions: Options

Possible Errors

OutOfMemory

Example

 test valueAlloc {
    const allocator = std.testing.allocator;
    const expected =
        \\{"foo":"bar","answer":42,"my_friend":"sammy"}
    ;
    const actual = try valueAlloc(allocator, .{ .foo = "bar", .answer = 42, .my_friend = "sammy" }, .{});
    defer allocator.free(actual);

    try std.testing.expectEqualStrings(expected, actual);
}

Source

  pub fn valueAlloc(gpa: Allocator, v: anytype, options: Options) error{OutOfMemory}![]u8 {
    var aw: Writer.Allocating = .init(gpa);
    defer aw.deinit();
    value(v, options, &aw.writer) catch return error.OutOfMemory;
    return aw.toOwnedSlice();
