Expand description

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

Variants

`Region(String)`

Low level error with mmap.

`CouldNotGrow`

Fields

current: Pages

The current size in pages.

attempted_delta: Pages

The attempted amount to grow by in pages.

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

`InvalidMemory`

Fields

reason: String

The reason why the provided memory is invalid.

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

`MinimumMemoryTooLarge`

Fields

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.

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

`MaximumMemoryTooLarge`

Fields

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.

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

`Generic(String)`

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