Struct DeserializerConfig 

pub struct DeserializerConfig { /* private fields */ }

Configures how pickles are deserialized.

The configuration is independent of the input so it can be created once (even as a constant) and used for many inputs. The method from_slice works like the function of the same name.

use deser_pickle::DeserializerConfig;

const CONFIG: DeserializerConfig = DeserializerConfig::new();
// `pickle.dumps([1, 2], 4)`
let input = b"\x80\x04\x95\x09\x00\x00\x00\x00\x00\x00\x00]\x94(K\x01K\x02e.";
assert_eq!(CONFIG.from_slice::<Vec<u32>>(input).unwrap(), [1, 2]);

Implementations

impl DeserializerConfig

pub const fn new() -> DeserializerConfig

Creates the default configuration.

pub const fn builder() -> DeserializerConfigBuilder

Returns a builder for the configuration (see DeserializerConfigBuilder).

pub const fn into_builder(self) -> DeserializerConfigBuilder

Returns a builder that starts with this configuration.

pub fn set_context(&mut self, context: Context)

Sets the context the values are deserialized in.

The values of the context are the defaults of the extension values of the state (see Context), for instance the variants of open enums. The deserializers and readers created with the configuration use this context. A context set on the driver takes precedence.

pub fn context(&self) -> &Context

Returns the context the values are deserialized in.

pub fn set_max_shared_events(&mut self, max: usize)

Limits the events of values that are emitted more than once.

Values that are reached more than once are emitted at every place (see References). A small pickle can reach the same values very often (each level of a list that holds the level below twice doubles the output), this limits the number of events that are emitted for values that were emitted before. The default is 1048576.

pub fn max_shared_events(&self) -> usize

Returns the limit of the events of values that are emitted more than once.

pub fn from_slice<'de, T: Deserialize<'de>>( &self, input: &'de [u8], ) -> Result<T, Error>

Deserializes a value.

See from_slice.

impl DeserializerConfig

pub fn reader<R: Read>(&self, reader: R) -> Reader<R, StreamDeserializer>

Creates a reader of values (see deser::io::Reader).

See StreamDeserializer.

pub fn from_reader<T: DeserializeOwned, R: Read>( &self, reader: R, ) -> Result<T, Error>

Deserializes a value from a reader.

See from_reader.
