Struct ChainsawDeserializer 

pub struct ChainsawDeserializer<'opts> { /* private fields */ }

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.

Implementations

impl<'opts> ChainsawDeserializer<'opts>

pub fn new(json_serialization_opts: &'opts JsonSerializationOpts) -> Self

Creates an instance of a ChainsawDeserializer. Make sure to use ChainsawDeserializer::add_idl_json for each program before attempting to deserialize accounts for it.

• [serialization_opts] specifying how specific data types should be deserialized.

pub fn add_idl_json( &mut self, program_id: String, idl_json: &str, provider: IdlProvider, ) -> ChainsawResult<()>

Parses an [IDL] specification from the provided [idl_json] for the [program_id] and adds a to the json/bson accounts deserializer derived from it.

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

pub fn has_idl(&self, program_id: &str) -> bool

Returns true if the IDL of the given [program_id] has been added to the deserializer.

pub fn added_idls(&self) -> HashSet<String>

Returns all program ids for which IDLs have been added to the deserializer.

pub fn deserialize_account_to_json_string( &self, program_id: &str, account_data: &mut &[u8], ) -> ChainsawResult<String>

Deserializes an account to a JSON string.

In order to specify a custom Write writer, i.e. a socket connection to write to, use [deserialize_account] instead.

• [program_id] is the program id of progra that owns the account. make sure to add it’s IDL before via ChainsawDeserializer::add_idl_json.
• [account_data] is the raw account data as a byte array

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

Deserializes an account and writes the resulting JSON to the provided Write write [f].

• [program_id] is the program id of progra that owns the account. make sure to add it’s IDL before via ChainsawDeserializer::add_idl_json.
• [account_data] is the raw account data as a byte array
• [f] is the Write writer to write the resulting JSON to, i.e. std::io::stdout() or String::new()
