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.
