Enum MemoryWriteError 

pub enum MemoryWriteError {
    PastEnd {
        offset: u64,
        length: usize,
        size: u64,
    },
    Shrank {
        before: u64,
        after: u64,
    },
    TooLarge(u64),
}

Why a memory write cannot be recorded.

Variants

PastEnd

The written bytes end past the size the memory is said to have after the write.

Fields

offset: u64

length: usize

size: u64

Shrank

The memory is said to have shrunk, which EVM memory never does within a frame.

Fields

before: u64

after: u64

TooLarge(u64)

More memory than this platform can address.

Trait Implementations

impl Clone for MemoryWriteError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryWriteError

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

Formats the value using the given formatter.

impl Display for MemoryWriteError

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

Formats the value using the given formatter.

impl Eq for MemoryWriteError

impl Error for MemoryWriteError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for MemoryWriteError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
