Enum BuildError

pub enum BuildError {
    EmptyRange,
    OverlappingRanges {
        prev: Range<usize>,
        next: Range<usize>,
    },
    OutOfBounds {
        range: Range<usize>,
        region_len: usize,
    },
}

Builder error for overlays (structure only; region bounds are checked at merge time).

Note: serialization assumes identical pointer width between sender and receiver, as Range<usize> is not portable across architectures. TODO: introduce a wire‐stable run type.

Variants

EmptyRange

A run with an empty range (start == end) was provided.

OverlappingRanges

Two runs overlap or are unsorted: prev.end > next.start. The offending ranges are returned for debugging.

Fields

prev: Range<usize>

next: Range<usize>

OutOfBounds

A run exceeds the region bounds when applying an overlay merge.

Fields

range: Range<usize>

region_len: usize

Trait Implementations

impl Clone for BuildError

fn clone(&self) -> BuildError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuildError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BuildError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Error for BuildError

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 BuildError

fn eq(&self, other: &BuildError) -> 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.

impl Serialize for BuildError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
