Fields

max_units: u64

Number of compute units that an instruction is allowed. Compute units are consumed by program execution, resources they use, etc…

log_64_units: u64

Number of compute units consumed by a log_u64 call

create_program_address_units: u64

Number of compute units consumed by a create_program_address call

invoke_units: u64

Number of compute units consumed by an invoke call (not including the cost incurred by the called program)

max_invoke_depth: usize

Maximum cross-program invocation depth allowed

sha256_base_cost: u64

Base number of compute units consumed to call SHA256

sha256_byte_cost: u64

Incremental number of units consumed by SHA256 (based on bytes)

max_call_depth: usize

Maximum BPF to BPF call depth

stack_frame_size: usize

Size of a stack frame in bytes, must match the size specified in the LLVM BPF backend

log_pubkey_units: u64

Number of compute units consumed by logging a Pubkey

max_cpi_instruction_size: usize

Maximum cross-program invocation instruction size

cpi_bytes_per_unit: u64

Number of account data bytes per conpute unit charged during a cross-program invocation

sysvar_base_cost: u64

Base number of compute units consumed to get a sysvar

secp256k1_recover_cost: u64

Number of compute units consumed to call secp256k1_recover

syscall_base_cost: u64

Number of compute units consumed to do a syscall without any work

heap_size: Option<usize>

Optional program heap region size, if None then loader default

heap_cost: u64

Number of compute units per additional 32k heap above the default (~.5 us per 32k at 15 units/us rounded up)
