Enum DumpOptionField

pub enum DumpOptionField<F: FieldId, A: AggField<F>> {
    Unit(DumpField<F>),
    Agg(A),
}

Generic representation of fields accepted by different dump subcommands. Each DumpOptionField is either an aggregation of multiple FieldIds, or a “unit” field which could be either a CommonField or a FieldId.

Variants

Unit(DumpField<F>)

Agg(A)

Trait Implementations

impl<F: Clone + FieldId, A: Clone + AggField<F>> Clone for DumpOptionField<F, A>

fn clone(&self) -> DumpOptionField<F, A>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: Debug + FieldId, A: Debug + AggField<F>> Debug for DumpOptionField<F, A>

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

Formats the value using the given formatter.

impl<F: FieldId + Display, A: AggField<F> + Display> Display for DumpOptionField<F, A>

Used for generating help string that lists all supported fields.

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

Formats the value using the given formatter.

impl<F: FieldId + FromStr, A: AggField<F> + FromStr> FromStr for DumpOptionField<F, A>

Used by Clap to parse user provided –fields.

fn from_str(s: &str) -> Result<Self, Self::Err>

When parsing command line options into DumpOptionField, priority order is CommonField, AggField, and then FieldId.

type Err = Error

The associated error which can be returned from parsing.

impl<F: PartialEq + FieldId, A: PartialEq + AggField<F>> PartialEq for DumpOptionField<F, A>

fn eq(&self, other: &DumpOptionField<F, A>) -> 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.
