Enum fst::raw::Error [−][src]
pub enum Error { Version { expected: u64, got: u64, }, Format { size: usize, }, ChecksumMismatch { expected: u32, got: u32, }, ChecksumMissing, DuplicateKey { got: Vec<u8>, }, OutOfOrder { previous: Vec<u8>, got: Vec<u8>, }, WrongType { expected: FstType, got: FstType, }, FromUtf8(FromUtf8Error), // some variants omitted }
Expand description
An error that occurred while using a finite state transducer.
This enum is non-exhaustive. New variants may be added to it in compatible releases.
Variants
A version mismatch occurred while reading a finite state transducer.
This occurs when the API version (of the crate) does not match the version encoded in the finite state transducer.
When this error is encountered, there are only two ways to fix it:
- Change the version of the library to one that is compatible with the given finite state transducer.
- Rebuild the finite state transducer.
Show fields
An unexpected error occurred while reading a finite state transducer. Usually this occurs because the data is corrupted or is not actually a finite state transducer serialized by this library.
Show fields
Fields of Format
size: usize
The number of bytes given to the FST constructor.
An error that is returned if verification of an FST fails because of a checksum mismatch.
Show fields
An error that is returned if the caller attempts to verify an FST
that does not have a checksum, as is the case for all FSTs generated
by this crate before version 0.4
.
A duplicate key was inserted into a finite state transducer, which is not allowed.
A key was inserted out of order into a finite state transducer.
Keys must always be inserted in lexicographic order.
Show fields
A finite state transducer with an unexpected type was found.
This is not currently used in this crate, but callers may wish to employ its use for alternative data structures implemented on top of finite state transducers.
Show fields
FromUtf8(FromUtf8Error)
An error that occurred when trying to decode a UTF-8 byte key.
