Function validate [src]

Alias for std.json.scanner.validate

Scan the input and check for malformed JSON. On SyntaxError or UnexpectedEndOfInput, returns false. Returns any errors from the allocator as-is, which is unlikely, but can be caused by extreme nesting depth in the input.

Prototype

pub fn validate(allocator: Allocator, s: []const u8) Allocator.Error!bool

Parameters

allocator: Allocators: []const u8

Source

  pub fn validate(allocator: Allocator, s: []const u8) Allocator.Error!bool {
    var scanner = Scanner.initCompleteInput(allocator, s);
    defer scanner.deinit();

    while (true) {
        const token = scanner.next() catch |err| switch (err) {
            error.SyntaxError, error.UnexpectedEndOfInput => return false,
            error.OutOfMemory => return error.OutOfMemory,
            error.BufferUnderrun => unreachable,
        };
        if (token == .end_of_document) break;
    }

    return true;
}
