Available on crate feature chimera only.

Native error code from the underlying chimera library.

Variants

Invalid = -1

A parameter passed to this function was invalid.

NoMem = -2

A memory allocation failed.

ScanTerminated = -3

The engine was terminated by callback.

This return value indicates that the target buffer was partially scanned, but that the callback function returned ChimeraMatchResult::Terminate after a match was located.

CompilerError = -4

The pattern compiler failed, and the ChimeraInnerCompileError should be inspected for more detail.

DbVersionError = -5

The given database was built for a different version of the Chimera matcher.

DbPlatformError = -6

The given database was built for a different platform (i.e., CPU type).

DbModeError = -7

The given database was built for a different mode of operation.

This error is returned when streaming calls are used with a non-streaming database and vice versa.

BadAlign = -8

A parameter passed to this function was not correctly aligned.

BadAlloc = -9

The memory allocator did not correctly return memory suitably aligned for the largest representable data type on this platform.

ScratchInUse = -10

The scratch region was already in use.

This error is returned when Chimera is able to detect that the scratch region given is already in use by another Chimera API call.

A separate scratch region, allocated with ChimeraScratch::setup_for_db() or ChimeraScratch::try_clone(), is required for every concurrent caller of the Chimera API.

For example, this error might be returned when ChimeraScratch::scan_sync() has been called inside a callback delivered by a currently-executing ChimeraScratch::scan_sync() call using the same scratch region.

Note: Not all concurrent uses of scratch regions may be detected. This error is intended as a best-effort debugging tool, not a guarantee.

Note: safe Rust code should never see this error; Arc::make_mut() is often an effective way to avoid this while preserving the ergonomics of a Clone and Send reference type. This approach is used in this library’s stream module.

UnknownError = -13

Unexpected internal error from Hyperscan.

This error indicates that there was unexpected matching behaviors from Hyperscan. This could be related to invalid usage of scratch space or invalid memory operations by users.

FailInternal = -32

Returned when pcre_exec (called for some expressions internally from ChimeraScratch::scan_sync()) failed due to a fatal error.

Trait Implementations

impl Clone for ChimeraRuntimeError

fn clone(&self) -> ChimeraRuntimeError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Ord for ChimeraRuntimeError

fn cmp(&self, other: &ChimeraRuntimeError) -> Ordering

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
