pub struct Payload { /* private fields */ }
Expand description

A wrapper type for the payload hashmap.

Implementations§

Create a new empty Payload.

Create a Payload from an array of key-value pairs, specified as (PayloadKey, PayloadType) tuples.

Inserts a key-value pair into the Payload. If the Payload did not have this key present, then None is returned. If the Payload did have this key present, the value is updated, and the old value is returned. The key is not updated, though; this matters for types that can be == without being identical. See std::collections::HashMap documentation for more info.

Tries to insert a key-value pair into a Payload. If this key is already in the Payload nothing is updated and an error is returned.

Returns a reference to the value corresponding to the key.

Get a reference to the Pubkey associated with a key, if and only if the Payload value is the PayloadType::Pubkey variant. Returns None if the key is not present in the Payload or the value is a different PayloadType variant.

Get a reference to the SeedsVec associated with a key, if and only if the Payload value is the PayloadType::Seeds variant. Returns None if the key is not present in the Payload or the value is a different PayloadType variant.

Get a reference to the ProofInfo associated with a key, if and only if the Payload value is the PayloadType::MerkleProof variant. Returns None if the key is not present in the Payload or the value is a different PayloadType variant.

Get the u64 associated with a key, if and only if the Payload value is the PayloadType::Number variant. Returns None if the key is not present in the Payload or the value is a different PayloadType variant.

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more

Returns the “default value” for a type. Read more
This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
