readUntilDelimiter

Deprecated: use streamUntilDelimiter with FixedBufferStream's writer instead. Reads from the stream until specified byte is found. If the buffer is not large enough to hold the entire contents, error.StreamTooLong is returned. If end-of-stream is found, error.EndOfStream is returned. Returns a slice of the stream data, with ptr equal to buf.ptr. The delimiter byte is written to the output buffer but is not included in the returned slice.

Function parameters

Parameters

self:Self
buf:[]u8
delimiter:u8

Optional parameters for `skipBytes`

Types

SkipBytesOptions: Optional parameters for `skipBytes`
Adapter

Returns the number of bytes read.

Functions

read: Returns the number of bytes read.
readAll: Returns the number of bytes read.
readAtLeast: Returns the number of bytes read, calling the underlying read
readNoEof: If the number read would be smaller than `buf.len`, `error.EndOfStream` is returned instead.
readAllArrayList: Appends to the `std.array_list.Managed` contents by reading from the stream
readAllArrayListAligned
readAllAlloc: Allocates enough memory to hold all the contents of the stream.
readUntilDelimiterArrayList: Deprecated: use `streamUntilDelimiter` with ArrayList's writer instead.
readUntilDelimiterAlloc: Deprecated: use `streamUntilDelimiter` with ArrayList's writer instead.
readUntilDelimiter: Deprecated: use `streamUntilDelimiter` with FixedBufferStream's writer instead.
readUntilDelimiterOrEofAlloc: Deprecated: use `streamUntilDelimiter` with ArrayList's (or any other's) writer instead.
readUntilDelimiterOrEof: Deprecated: use `streamUntilDelimiter` with FixedBufferStream's writer instead.
streamUntilDelimiter: Appends to the `writer` contents by reading from the stream until `delimiter` is found.
skipUntilDelimiterOrEof: Reads from the stream until specified byte is found, discarding all data,
readByte: Reads 1 byte from the stream or returns `error.EndOfStream`.
readByteSigned: Same as `readByte` except the returned byte is signed.
readBytesNoEof: Reads exactly `num_bytes` bytes and returns as an array.
readInt
readVarInt
skipBytes: Reads `num_bytes` bytes from the stream and discards them
isBytes: Reads `slice.len` bytes from the stream and returns if they are the same as the passed slice
readStruct
readStructEndian
readEnum: Reads an integer with the same size as the given enum's tag type.
discard: Reads the stream until the end, ignoring all the data.
adaptToNewApi: Helper for bridging to the new `Reader` API while upgrading.

Implementation

pub fn readUntilDelimiter(self: Self, buf: []u8, delimiter: u8) anyerror![]u8 {
    var fbs = std.io.fixedBufferStream(buf);
    try self.streamUntilDelimiter(fbs.writer(), delimiter, fbs.buffer.len);
    const output = fbs.getWritten();
    buf[output.len] = delimiter; // emulating old behaviour
    return output;
}
