Enum Verbosity 

pub enum Verbosity {
    Quiet,
    NoWarnings,
    Normal,
    Verbose,
}

The requested verbosity of output.

Ordering

Verbosity::Quiet < Verbosity::NoWarnings < Verbosity::Normal < Verbosity::Verbose

Variants

Quiet

Avoid printing anything to standard output.

String representation: quiet.

NoWarnings

Avoid printing warnings to standard output.

String representation: no-warnings.

Normal

Default verbosity level.

String representation: normal.

Verbose

Print extra information to standard output.

String representation: verbose.

Implementations

impl Verbosity

pub fn from_env_var(env_var_name: &str) -> Result<Self>

Get the verbosity level from the given environment variable.

Environment variable value is decoding using Verbosity::from_str. See Verbosity variants documentation for valid values.

pub fn is_default(&self) -> bool

Check if the verbosity level is the default one.

Trait Implementations

impl Clone for Verbosity

fn clone(&self) -> Verbosity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Verbosity

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

Formats the value using the given formatter.

impl Default for Verbosity

fn default() -> Verbosity

Returns the “default value” for a type.

impl Display for Verbosity

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

Formats the value using the given formatter.

impl From<VerbositySpec> for Verbosity

fn from(spec: VerbositySpec) -> Self

Converts to this type from the input type.

impl Ord for Verbosity

fn cmp(&self, other: &Verbosity) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Verbosity

fn eq(&self, other: &Verbosity) -> 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 PartialOrd for Verbosity

fn partial_cmp(&self, other: &Verbosity) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl ValueEnum for Verbosity

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
