Enum CopyReadError 

pub enum CopyReadError {
    BufferTooShort {
        type_name: &'static str,
        expected: usize,
        actual: usize,
    },
    LengthExceedsBuffer {
        declared: usize,
        available: usize,
    },
}

Errors that can occur when reading HyperBinary COPY data.

Variants

BufferTooShort

Buffer is too short to read the expected type.

Fields

type_name: &'static str

The type being read (e.g., “i16”, “i32”, “varbinary”).

expected: usize

The expected minimum buffer size.

actual: usize

The actual buffer size.

LengthExceedsBuffer

The declared length in a variable-length field exceeds available data.

Fields

declared: usize

The declared length from the length prefix.

available: usize

The available buffer space after the length prefix.

Trait Implementations

impl Clone for CopyReadError

fn clone(&self) -> CopyReadError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CopyReadError

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

Formats the value using the given formatter.

impl Display for CopyReadError

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

Formats the value using the given formatter.

impl Error for CopyReadError

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 CopyReadError

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