Expand description

Represents an error encountered while using Hard.

Variants§

§

AllocationFailed(Errno)

sodium_malloc returned an error when we tried to allocate a region of memory.

This is most likely to occur if there is not sufficient memory to allocate, but could occur for other reasons. The associated value contains the value of the errno value, which is set if sodium_malloc fails.

§

MprotectNoAccessFailed(Errno)

sodium_mprotect_noaccess returned an error.

This is most likely to occur if the platform we’re running on doesn’t have the mprotect syscall (or its equivalent).

§

MprotectReadOnlyFailed(Errno)

sodium_mprotect_readonly returned an error.

This is most likely to occur if the platform we’re running on doesn’t have the mprotect syscall (or its equivalent).

§

MprotectReadWriteFailed(Errno)

sodium_mprotect_readwrite returned an error.

This is most likely to occur if the platform we’re running on doesn’t have the mprotect syscall (or its equivalent).

§

InitFailed

sodium_init returned an error.
