Struct Core

pub struct Core<Id: SiteId, Cx: CoreExt, const CALL_STACK_SIZE: usize = { CALL_STACK_SIZE_MAX as usize }> {
    pub cx: Cx,
    /* private fields */
}

Registers of a single CPU/VM core.

Fields

cx: Cx

Core extension module.

Implementations

impl<Id: SiteId, Cx: CoreExt, const CALL_STACK_SIZE: usize> Core<Id, Cx, CALL_STACK_SIZE>

pub fn new() -> Self

Initializes registers. Sets CK to true, counters to zero, call stack to empty and the rest of registers to None value.

An alias for Core::with(CoreConfig::default(), Cx::default()).

pub fn with(config: CoreConfig, cx_config: Cx::Config) -> Self

Initializes registers using a configuration object CoreConfig.

pub fn reset(&mut self)

Reset the core extension by setting all the registers to None.

impl<Id: SiteId, Cx: CoreExt, const CALL_STACK_SIZE: usize> Core<Id, Cx, CALL_STACK_SIZE>

Microcode for flag registers.

pub fn co(&self) -> Status

Read overflow/carry flag.

pub fn set_co(&mut self, co: Status)

Set overflow/carry flag to a value.

pub fn cf(&self) -> u64

Return how many times ck was set to a failed state.

pub fn has_failed(&self) -> bool

Return true if ck was in a failed state for at least once.

pub fn ck(&self) -> Status

Return whether check register ck is in a failed state.

pub fn reset_ck(&mut self)

Reset CK register.

pub fn cp(&self) -> u16

Return the size of the call stack.

pub fn push_cs(&mut self, from: Site<Id>) -> Option<u16>

Push a location to a call stack.

Returns

Top of the call stack.

pub fn pop_cs(&mut self) -> Option<Site<Id>>

Pops a call stack item.

pub fn cl(&self) -> Option<u64>

Return complexity limit value.

pub fn acc_complexity(&mut self, complexity: u64) -> bool

Accumulate complexity value.

Returns

Boolean indicating whether the complexity limit is reached.

pub fn get(&self, reg: Cx::Reg) -> Option<<Cx::Reg as Register>::Value>

Get register value.

Trait Implementations

impl<Id: Clone + SiteId, Cx: Clone + CoreExt, const CALL_STACK_SIZE: usize> Clone for Core<Id, Cx, CALL_STACK_SIZE>

fn clone(&self) -> Core<Id, Cx, CALL_STACK_SIZE>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Id: SiteId, Cx: CoreExt, const CALL_STACK_SIZE: usize> Default for Core<Id, Cx, CALL_STACK_SIZE>

fn default() -> Self

Returns the “default value” for a type.

impl<Id: SiteId, Cx: CoreExt + Supercore<Cx2>, Cx2: CoreExt, const CALL_STACK_SIZE: usize> Supercore<Core<Id, Cx2, CALL_STACK_SIZE>> for Core<Id, Cx, CALL_STACK_SIZE>

fn subcore(&self) -> Core<Id, Cx2, CALL_STACK_SIZE>
