Expand description

Error type describing things that can go wrong when operating on Wasm Memories.

Variants

Region(String)

Low level error with mmap.

CouldNotGrow

The operation would cause the size of the memory to exceed the maximum or would cause an overflow leading to unindexable memory.

Show fields

Fields of CouldNotGrow

current: Pages

The current size in pages.

attempted_delta: Pages

The attempted amount to grow by in pages.

InvalidMemory

The operation would cause the size of the memory size exceed the maximum.

Show fields

Fields of InvalidMemory

reason: String

The reason why the provided memory is invalid.

MinimumMemoryTooLarge

Caller asked for more minimum memory than we can give them.

Show fields

Fields of MinimumMemoryTooLarge

min_requested: Pages

The number of pages requested as the minimum amount of memory.

max_allowed: Pages

The maximum amount of memory we can allocate.

MaximumMemoryTooLarge

Caller asked for a maximum memory greater than we can give them.

Show fields

Fields of MaximumMemoryTooLarge

max_requested: Pages

The number of pages requested as the maximum amount of memory.

max_allowed: Pages

The number of pages requested as the maximum amount of memory.

Generic(String)

A user defined error value, used for error cases not listed above.
