Struct AccessTracker

Source 
pub struct AccessTracker {
    pub this_container_code_type: Option<CodeType>,
    pub codes: Vec<bool>,
    pub processing_stack: Vec<usize>,
    pub subcontainers: Vec<Option<CodeType>>,
}

Fields§

§this_container_code_type: Option<CodeType>

This code type

§codes: Vec<bool>

Vector of accessed codes.

§processing_stack: Vec<usize>

Stack of codes section that needs to be processed.

§subcontainers: Vec<Option<CodeType>>

Code accessed by subcontainer and expected subcontainer first code type. EOF code can be invoked in EOFCREATE mode or used in RETURNCONTRACT opcode. if SubContainer is called from EOFCREATE it needs to be ReturnContract type. If SubContainer is called from RETURNCONTRACT it needs to be ReturnOrStop type.

None means it is not accessed.

Implementations§

Source§

impl AccessTracker

Source

pub fn new( this_container_code_type: Option<CodeType>, codes_size: usize, subcontainers_size: usize, ) -> Self

Returns a new instance of CodeSubContainerAccess.

Mark first code section as accessed and push first it to the stack.

§Panics

Panics if codes_size is zero.

Source

pub fn access_code(&mut self, index: usize)

Mark code as accessed.

If code was not accessed before, it will be added to the processing stack.

Assumes that index is valid.

Source

pub fn set_subcontainer_type( &mut self, index: usize, new_code_type: CodeType, ) -> Result<(), EofValidationError>
