Struct sp1_core::runtime::SyscallContext

pub struct SyscallContext<'a, 'b: 'a> {
    pub clk: u32,
    pub syscall_lookup_id: u128,
    /* private fields */
}

A runtime for syscalls that is protected so that developers cannot arbitrarily modify the runtime.

Fields

clk: u32

syscall_lookup_id: u128

Implementations

impl<'a, 'b> SyscallContext<'a, 'b>

pub fn new(runtime: &'a mut Runtime<'b>) -> Self

pub fn record_mut(&mut self) -> &mut ExecutionRecord

pub fn current_shard(&self) -> u32

pub fn current_channel(&self) -> u32

pub fn mr(&mut self, addr: u32) -> (MemoryReadRecord, u32)

pub fn mr_slice( &mut self, addr: u32, len: usize, ) -> (Vec<MemoryReadRecord>, Vec<u32>)

pub fn mw(&mut self, addr: u32, value: u32) -> MemoryWriteRecord

pub fn mw_slice(&mut self, addr: u32, values: &[u32]) -> Vec<MemoryWriteRecord>

pub fn register_unsafe(&self, register: Register) -> u32

Get the current value of a register, but doesn’t use a memory record. This is generally unconstrained, so you must be careful using it.

pub fn byte_unsafe(&self, addr: u32) -> u8

pub fn word_unsafe(&self, addr: u32) -> u32

pub fn slice_unsafe(&self, addr: u32, len: usize) -> Vec<u32>

pub fn set_next_pc(&mut self, next_pc: u32)

pub fn set_exit_code(&mut self, exit_code: u32)
