Enum ZeroTrieBuildError 

#[non_exhaustive]
pub enum ZeroTrieBuildError {
    NonAsciiError,
    CapacityExceeded,
    CouldNotSolvePerfectHash,
    MixedCase,
    IllegalDelimiter,
}

Error types for the zerotrie crate.

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.

NonAsciiError

Non-ASCII data was added to an ASCII-only trie.

CapacityExceeded

The trie reached its maximum supported capacity.

CouldNotSolvePerfectHash

The builder could not solve the perfect hash function.

MixedCase

Mixed-case data was added to a case-insensitive trie.

IllegalDelimiter

Strings were added to a trie containing the delimiter.

Examples

use std::collections::BTreeMap;
use zerotrie::dense::ZeroAsciiDenseSparse2dTrieOwned;
use zerotrie::ZeroTrieBuildError;

let mut data: BTreeMap<&str, BTreeMap<&str, usize>> = BTreeMap::new();

// Delimiter in a prefix
data.entry("aa/bb").or_default().insert("CCC", 1);
let err =
    ZeroAsciiDenseSparse2dTrieOwned::try_from_btree_map_str(&data, b'/')
        .unwrap_err();
assert_eq!(err, ZeroTrieBuildError::IllegalDelimiter);

// Delimiter in a suffix
data.clear();
data.entry("aaa").or_default().insert("BB/CC", 1);
let err =
    ZeroAsciiDenseSparse2dTrieOwned::try_from_btree_map_str(&data, b'/')
        .unwrap_err();
assert_eq!(err, ZeroTrieBuildError::IllegalDelimiter);

Trait Implementations

impl Clone for ZeroTrieBuildError

fn clone(&self) -> ZeroTrieBuildError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ZeroTrieBuildError

impl Debug for ZeroTrieBuildError

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

Formats the value using the given formatter.

impl Display for ZeroTrieBuildError

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

Formats the value using the given formatter.

impl Eq for ZeroTrieBuildError

impl Error for ZeroTrieBuildError

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 ZeroTrieBuildError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
