Methods from Deref<Target = Bytecode>§

Source

Returns true if bytecode is EOF.

Source

pub fn is_eip7702(&self) -> bool

Returns a reference to the bytecode.

In case of EOF this will be the all code sections.

Source

pub fn bytecode_ptr(&self) -> *const u8

Note: EOF will return the pointer to the start of the code section. while legacy bytecode will point to the start of the bytes.

Returns raw bytes reference.
