Zig 0.17.0-dev (Split by item)

This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig library itself.

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.

static.parseFromTokenSource

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