Enum DfaCompileError 

#[non_exhaustive]
pub enum DfaCompileError {
    TooLarge {
        requested_bytes: usize,
        budget_bytes: usize,
        state_count: u32,
    },
    TrieStateCapExceeded {
        state_cap: usize,
    },
}

Structured failure from dfa_compile_with_budget.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TooLarge

Built DFA would exceed the caller’s transition-table budget.

Fields

requested_bytes: usize

Number of bytes the naive table would require.

budget_bytes: usize

Caller-supplied budget.

state_count: u32

State count at the point of budget exhaustion.

TrieStateCapExceeded

Trie grew past the permitted state cap during construction.

Fields

state_cap: usize

State cap derived from the caller-supplied budget.

Trait Implementations

impl Clone for DfaCompileError

fn clone(&self) -> DfaCompileError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DfaCompileError

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

Formats the value using the given formatter.

impl Display for DfaCompileError

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

Formats the value using the given formatter.

impl Error for DfaCompileError

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.
