Struct FieldTypeMismatch 

pub struct FieldTypeMismatch {
    pub field_path: String,
    pub expected: FieldRef,
    pub actual: FieldRef,
}

An array whose Arrow type or extension differs from the field the file schema records for it.

Returned as the source of an Error::InvalidInput by the file writers.

Fields

field_path: String

Dot-separated path of the mismatched field, starting at the top-level column.

expected: FieldRef

The field the file schema records.

actual: FieldRef

The field the input carries. A column written on its own is a bare array, so it carries no extension.

Trait Implementations

impl Clone for FieldTypeMismatch

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 FieldTypeMismatch

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

Formats the value using the given formatter.

impl Display for FieldTypeMismatch

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

Formats the value using the given formatter.

impl Eq for FieldTypeMismatch

impl Error for FieldTypeMismatch

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 FieldTypeMismatch

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

Equality operator ==.

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

Inequality operator !=.
