Variants

PatternCountOverflow

Pattern count does not fit the GPU ABI’s u32 pattern id field.

Fields

count: usize

Number of patterns supplied by the caller.

PatternLengthOverflow

One literal length does not fit the GPU ABI’s u32 length field.

Fields

pattern_index: usize

Index of the oversized pattern.

len: usize

UTF-8 byte length of the oversized pattern.

StateCountOverflow

Total NFA state count overflowed the GPU ABI’s u32 state id field.

TableWordCountOverflow

Transition or epsilon table word count overflowed host usize.

Fields

table: &'static str

Table being built.

StorageReserveFailed

Compiler staging allocation failed.

Fields

field: &'static str

Scratch vector being reserved.

requested: usize

Requested target capacity.

message: String

Allocator failure details.

Trait Implementations

impl Clone for NfaCompileError

fn clone(&self) -> NfaCompileError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NfaCompileError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for NfaCompileError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for NfaCompileError

impl Error for NfaCompileError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for NfaCompileError

fn eq(&self, other: &NfaCompileError) -> bool

Equality operator ==.

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

Inequality operator !=.
