Enum DescribeError 

pub enum DescribeError {
    Expressions {
        expression_schema: HashMap<String, ColumnType>,
        errors: HashMap<String, ExpressionError>,
    },
    Config(String),
}

Why Table::describe rejected a config.

Variants

Expressions

At least one expression failed to compile.

Fields

expression_schema: HashMap<String, ColumnType>

errors: HashMap<String, ExpressionError>

Config(String)

Every expression compiled but the rest of the config is invalid.

Trait Implementations

impl Clone for DescribeError

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 DescribeError

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

Formats the value using the given formatter.

impl Display for DescribeError

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

Formats the value using the given formatter.

impl Error for DescribeError

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 DescribeError

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

Equality operator ==.

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

Inequality operator !=.
