pub struct Encoder<W> { /* private fields */ }
Expand description

A non-allocating CBOR encoder writing encoded bytes to the given Write sink.

Implementations

Construct an Encoder that writes to the given Write sink.

Get back the Write impl.

Encode any type that implements Encode.

Encode a u8 value.

Encode an i8 value.

Encode a u16 value.

Encode an i16 value.

Encode a u32 value.

Encode an i32 value.

Encode a u64 value.

Encode an i64 value.

Encode a CBOR null value.

Encode a CBOR undefined value.

Encode a CBOR simple value.

Encode an f32 value as a half float (f16).

Requires feature "half".

NB: The conversion from f32 to f16 is potentially lossy. Generally values are truncated and rounded to the nearest 16-bit value, except:

  • 32-bit values which do not fit into 16 bit become ±∞.
  • 32-bit subnormal values become ±0.
  • Exponents smaller than the min. 16-bit exponent become 16-bit subnormals or ±0.

For further details please consult the half crate which is used internally for f16 support.

Encode an f32 value.

Encode an f64 value.

Encode a bool value.

Encode a char value.

Encode a CBOR tag.

Encode a byte slice.

Encode a string slice.

Begin encoding an array with len elements.

Begin encoding a map with len entries.

Begin encoding an array of unknown size.

Use Encoder::end to terminate the array.

Begin encoding an indefinite number of byte slices.

Use Encoder::end to terminate.

Begin encoding a map of unknown size.

Use Encoder::end to terminate the map.

Begin encoding an indefinite number of string slices.

Use Encoder::end to terminate.

Terminate an indefinite collection.

Syntactic sugar for Ok(()).
