Enum MemoryError

Source
#[non_exhaustive]
#[repr(u32)]
pub enum MemoryError { RuntimeAllocOutOfBounds = 200, AccessOutOfBounds = 201, }
Expand description

Memory error.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

RuntimeAllocOutOfBounds = 200

The error occurs, when program tries to allocate in block-chain runtime more memory than allowed.

§

AccessOutOfBounds = 201

The error occurs in attempt to access memory outside wasm program memory.
