Struct SignerPda 

pub struct SignerPda<'a, 'b> {
    pub pda: Pubkey,
    pub bump: [u8; 1],
    pub seeds: &'b [&'a [u8]],
}

PDA with easy access to its signer seeds.

Fields

pda: Pubkey

bump: [u8; 1]

seeds: &'b [&'a [u8]]

Implementations

impl<'a, 'b> SignerPda<'a, 'b>

pub fn new_checked( seeds: &'b [&'a [u8]], program_id: &Pubkey, expected: &AccountInfo<'_>, ) -> Result<Self, ProgramError>

Computes a new PDA and checks whether it matches the expected address.

pub fn check_owner( seeds: &'b [&'a [u8]], program_id: &Pubkey, owner: &Pubkey, expected: &AccountInfo<'_>, ) -> Result<(), ProgramError>

Checks whether there’s an existing PDA account with the provided owner.

pub fn signer_seeds(&'a self) -> Vec<&'a [u8]>

Returns the signer seeds (seeds + bump seed) of the PDA.
