Struct JsonAccountsDeserializer 

pub struct JsonAccountsDeserializer<'opts> {
    pub idl: Idl,
    pub provider: IdlProvider,
    pub account_deserializers: HashMap<DiscriminatorBytes, JsonIdlTypeDefinitionDeserializer<'opts>>,
    pub account_discriminators: HashMap<String, DiscriminatorBytes>,
    pub account_names: HashMap<DiscriminatorBytes, String>,
    pub type_map: JsonTypeDefinitionDeserializerMap<'opts>,
    pub serialization_opts: &'opts JsonSerializationOpts,
}

Setup to deserialize accounts for a given program. The accounts are expected to have been serialized using the borsh format.

Uses deserializers defined inside [deserializer] modules under the hood in order to resolve the appropriate borsh deserializers for each field.

Fields

idl: Idl

The parsed Idl of the program

provider: IdlProvider

The IdlProvider of the program

account_deserializers: HashMap<DiscriminatorBytes, JsonIdlTypeDefinitionDeserializer<'opts>>

The deserializers for accounts of this program keyed by the discriminator of each account type.

account_discriminators: HashMap<String, DiscriminatorBytes>

Allows looking up a discriminator for an account by name.

account_names: HashMap<DiscriminatorBytes, String>

Allows looking up a account names by discriminator.

type_map: JsonTypeDefinitionDeserializerMap<'opts>

Map of defined type deserializers. Defined types are be nested inside accounts.

serialization_opts: &'opts JsonSerializationOpts

The JsonSerializationOpts specifying how specific data types should be deserialized.

Implementations

impl<'opts> JsonAccountsDeserializer<'opts>

pub fn try_from_idl( json: &str, provider: IdlProvider, serialization_opts: &'opts JsonSerializationOpts, ) -> ChainsawResult<Self>

Tries to create an [AccounbtDeserializer] by parsing the Idl. Fails if the IDL could not be parsed.

• [json} the IDL definition in JSON format
• [provider] the provider used to create the IDL
• [serialization_opts] specifying how specific data types should be deserialized.

pub fn from_idl( idl: Idl, provider: IdlProvider, serialization_opts: &'opts JsonSerializationOpts, ) -> Self

Creates an [AccounbtDeserializer] from the provided Idl Fails if the IDL could not be parsed.

• [idl} the IDL definition
• [provider] the provider used to create the IDL
• [serialization_opts] specifying how specific data types should be deserialized.

pub fn deserialize_account_data<W: Write>( &self, account_data: &mut &[u8], f: &mut W, ) -> ChainsawResult<()>

Deserializes an account from the provided data.

This is the common way of resolving an account json and using it to deserialize account data. It expects the first 8 bytes of data to hold the account discriminator as is the case for anchor accounts. For all other accounts use [deserialize_account_data_by_name] instead.

pub fn deserialize_account_data_by_name<W: Write>( &self, account_data: &mut &[u8], account_name: &str, f: &mut W, ) -> ChainsawResult<()>

Deserializes an account from the provided data.

This method expects account data to not be prefixed with 8 bytes of discriminator data. Instead it derives that discriminator from the provided account name and then looks up the json.

pub fn account_name(&self, discriminator: &DiscriminatorBytes) -> Option<&str>

Resolves the account name for the provided discriminator.
