Struct anchor_lang::context::Context

source ·
pub struct Context<'a, 'b, 'c, 'info, T: Bumps> {
    pub program_id: &'a Pubkey,
    pub accounts: &'b mut T,
    pub remaining_accounts: &'c [AccountInfo<'info>],
    pub bumps: T::Bumps,
}
Expand description

Provides non-argument inputs to the program.

§Example

pub fn set_data(ctx: Context<SetData>, age: u64, other_data: u32) -> Result<()> {
    // Set account data like this
    (*ctx.accounts.my_account).age = age;
    (*ctx.accounts.my_account).other_data = other_data;
    // or like this
    let my_account = &mut ctx.account.my_account;
    my_account.age = age;
    my_account.other_data = other_data;
    Ok(())
}

Fields§

§program_id: &'a Pubkey

Currently executing program id.

§accounts: &'b mut T

Deserialized accounts.

§remaining_accounts: &'c [AccountInfo<'info>]

Remaining accounts given but not deserialized or validated. Be very careful when using this directly.

§bumps: T::Bumps

Bump seeds found during constraint validation. This is provided as a convenience so that handlers don’t have to recalculate bump seeds or pass them in as arguments. Type is the bumps struct generated by #[derive(Accounts)]
