Function parseFromTokenSource [src]

Alias for std.json.static.parseFromTokenSource

scanner_or_reader must be either a *std.json.Scanner with complete input or a *std.json.Reader. Note that error.BufferUnderrun is not actually possible to return from this function.

Prototype

 pub fn parseFromTokenSource( comptime T: type, allocator: Allocator, scanner_or_reader: anytype, options: ParseOptions, ) ParseError(@TypeOf(scanner_or_reader.*))!Parsed(T)

Parameters

T: typeallocator: Allocatoroptions: ParseOptions

Source

  pub fn parseFromTokenSource(
    comptime T: type,
    allocator: Allocator,
    scanner_or_reader: anytype,
    options: ParseOptions,
) ParseError(@TypeOf(scanner_or_reader.*))!Parsed(T) {
    var parsed = Parsed(T){
        .arena = try allocator.create(ArenaAllocator),
        .value = undefined,
    };
    errdefer allocator.destroy(parsed.arena);
    parsed.arena.* = ArenaAllocator.init(allocator);
    errdefer parsed.arena.deinit();

    parsed.value = try parseFromTokenSourceLeaky(T, parsed.arena.allocator(), scanner_or_reader, options);

    return parsed;
