Struct AdaptiveConfig 

pub struct AdaptiveConfig { /* private fields */ }

Available on crate feature adaptive only.

Data-aware encoding configuration.

Implementations

impl AdaptiveConfig

pub const fn base_config(self) -> Config

Returns the variable-integer payload configuration.

pub fn serialize<T: NsonSerialize + ?Sized>(self, value: &T) -> Result<Vec<u8>>

Available on crate feature alloc only.

Uses value-width adaptive varints for a regular nextjson payload.

pub fn deserialize<'de, T: NsonDeserialize<'de>>( self, input: &'de [u8], ) -> Result<T>

Decodes a regular value-width adaptive nextjson payload.

pub fn encode_string(self, value: &str) -> Result<Vec<u8>>

Available on crate feature alloc only.

Encodes a string using raw UTF-8 or 7-bit ASCII packing, whichever is smaller.

pub fn encoded_string_size(self, value: &str) -> Result<usize>

Returns the exact adaptive string frame size without allocating.

pub fn encode_string_into_slice( self, output: &mut [u8], value: &str, ) -> Result<usize>

Encodes a string into caller-owned memory without allocating.

The output is left untouched when it is too small.

pub fn string_strategy(self, input: &[u8]) -> Result<StringStrategy>

Returns the strategy tag without decoding the string.

pub fn decode_string(self, input: &[u8]) -> Result<String>

Available on crate feature alloc only.

Decodes and validates an adaptively encoded string.

pub fn decode_string_into_slice<'output>( self, output: &'output mut [u8], input: &[u8], ) -> Result<&'output str>

Decodes a string into caller-owned UTF-8 storage without allocating.

The returned string borrows output. Raw UTF-8 is copied into the destination; use Self::decode_string_borrowed when borrowing the encoded frame directly is preferable. The output is left untouched when its capacity is smaller than the declared decoded length.

pub fn decode_string_borrowed<'a>(self, input: &'a [u8]) -> Result<Cow<'a, str>>

Available on crate feature alloc only.

Decodes a string while borrowing raw UTF-8 payloads directly from input.

ASCII7 payloads require expansion and are therefore returned as owned strings. The returned Cow makes that distinction explicit.

pub fn encode_i64_slice(self, values: &[i64]) -> Result<Vec<u8>>

Available on crate feature alloc only.

Encodes an i64 slice using raw, delta, or run-length varints.

pub fn encoded_i64_slice_size(self, values: &[i64]) -> Result<usize>

Returns the exact adaptive integer-collection frame size without allocating.

pub fn encode_i64_slice_into_slice( self, output: &mut [u8], values: &[i64], ) -> Result<usize>

Encodes an integer collection into caller-owned memory without allocating.

The output is left untouched when it is too small.

pub fn collection_strategy(self, input: &[u8]) -> Result<CollectionStrategy>

Returns the collection strategy tag without decoding all values.

pub fn decode_i64_vec(self, input: &[u8]) -> Result<Vec<i64>>

Available on crate feature alloc only.

Decodes an adaptive i64 collection with checked delta reconstruction.

pub fn decoded_i64_slice_len(self, input: &[u8]) -> Result<usize>

Returns the declared decoded element count after validating the frame header.

pub fn decode_i64_slice_into( self, output: &mut [i64], input: &[u8], ) -> Result<usize>

Decodes an adaptive integer collection into caller-owned memory.

This path performs no heap allocation. The output is left untouched when it is smaller than the decoded collection length.
