Enum CanonicalizeError 

#[non_exhaustive]
pub enum CanonicalizeError {
    Parse(String),
    InputTooLong {
        limit: usize,
    },
    TooDeep {
        limit: usize,
    },
    NotRoundTrippable(String),
    Unsupported(String),
}

Why a predicate could not be turned into canonical text.

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.

Parse(String)

The SQL did not parse. The message comes from the parser.

InputTooLong

The input was longer than the crate will accept. Shortening it may succeed.

Fields

limit: usize

TooDeep

The expression nested deeper than the crate will walk. Simplifying it may succeed.

Fields

limit: usize

NotRoundTrippable(String)

The predicate has no canonical spelling the parser can read back unchanged, so hashing it would risk giving two different predicates one key.

Unsupported(String)

Syntax this crate does not canonicalize.

Trait Implementations

impl Clone for CanonicalizeError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CanonicalizeError

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

Formats the value using the given formatter.

impl Display for CanonicalizeError

Formats the value using the given formatter.

impl Eq for CanonicalizeError

impl Error for CanonicalizeError

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 CanonicalizeError

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

Equality operator ==.

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

Inequality operator !=.
