Create an empty output, reserving enough space for the specified number of bytes in the destination buffer.
init(capacity: Int) The size hint is only effective if Destination provides a real, non-defaulted witness for RangeReplaceableCollection.reserveCapacity(_:).
import BSONABIModels the BSON type system and the binary interface of the BSON serialization format.
@frozen struct Output@frozen enum BSONThe namespace for all BSON types.
@frozen struct IntA signed integer value type.
mutating func reserveCapacity(_ n: Int) Prepares the collection to store the specified number of elements, when doing so is appropriate for the underlying type.
protocol RangeReplaceableCollection<Element> : Collection where Self.SubSequence : RangeReplaceableCollectionA collection that supports replacement of an arbitrary subrange of elements with the elements of another collection.
init(preallocated destination: ArraySlice<UInt8>) Create an output with a pre-allocated destination buffer. The buffer does not need to be empty, and existing data will not be cleared.
var destination: ArraySlice<UInt8>subscript<Encoder>(as _: Encoder.Type) -> Encoder where Encoder : BSON.Encoder { mutating get set } Temporarily rebinds this output’s storage buffer to an encoder of the specified type. This function does not add any headers or trailers; to emit a complete BSON frame, mutate through subscript(as:in:).
subscript<Encoder>(as _: Encoder.Type, in frame: BSON.DocumentFrame.Type) -> Encoder where Encoder : BSON.Encoder { mutating get set } Temporarily rebinds this output’s storage buffer to an encoder of the specified type, bracketing it with the appropriate headers or trailers.
subscript(with key: BSON.Key) -> BSON.FieldEncoder { get set } Temporarily rebinds this output’s storage buffer to a field encoder. Field encoding is always lazy, so the getter has no effects.
mutating func append(_ byte: UInt8) Appends a single byte to the output destination.
mutating func append(_ bytes: some Sequence<UInt8>) Appends a sequence of bytes to the output destination.
mutating func reserve(another bytes: Int) Reserves another bytes worth of capacity in the output destination, in addition to the bytes already present.
mutating func serialize(fields: some Sequence<(key: BSON.Key, value: BSON.AnyValue)>) mutating func serialize(id: BSON.Identifier) mutating func serialize(key: BSON.Key, value: BSON.AnyValue) Serializes the raw type code of the given variant value, followed by the field key (with a trailing null byte), followed by the variant value itself.
mutating func serialize(type: BSON.AnyType) mutating func serialize(variant: BSON.AnyValue) Serializes the given variant value, without encoding its type.
