Implementations

impl Verbosity

pub fn level() -> Self

Gets the global Verbosity level

Verbosity::Verbose.set_as_global();

assert_eq!(Verbosity::level(), Verbosity::Verbose);

pub fn is_quite() -> bool

Checks if global Verbosity level is Quite

Verbosity::Quite.set_as_global();

assert_eq!(Verbosity::level(), Verbosity::Quite);

pub fn is_terse() -> bool

Checks if global Verbosity level is Terse

• is not terse if level is ‘Quite’

Verbosity::Quite.set_as_global();

assert_eq!(Verbosity::level(), Verbosity::Quite);
assert!(!Verbosity::is_terse())

• is terse if level is Terse

Verbosity::Terse.set_as_global();

assert_eq!(Verbosity::level(), Verbosity::Terse);
assert!(Verbosity::is_terse())

• is terse also if level is ‘Verbose’

Verbosity::Verbose.set_as_global();

assert_eq!(Verbosity::level(), Verbosity::Verbose);
assert!(Verbosity::is_terse())

pub fn is_verbose() -> bool

Checks if global Verbosity level is ‘Verbose’

• is not verbose if level is ‘Quite’

Verbosity::Quite.set_as_global();

assert_eq!(Verbosity::level(), Verbosity::Quite);
assert!(!Verbosity::is_verbose())

• is not verbose if level is Terse

Verbosity::Terse.set_as_global();

assert_eq!(Verbosity::level(), Verbosity::Terse);
assert!(!Verbosity::is_verbose())

• is verbose if level is ‘Verbose’

Verbosity::Verbose.set_as_global();

assert_eq!(Verbosity::level(), Verbosity::Verbose);
assert!(Verbosity::is_verbose())

pub fn set_as_global(self)

Sets the instance of a Verbosity level as the global level

Verbosity::Verbose.set_as_global();

assert_eq!(Verbosity::level(), Verbosity::Verbose);

Verbosity::Quite.set_as_global();

assert_ne!(Verbosity::level(), Verbosity::Quite);
assert_eq!(Verbosity::level(), Verbosity::Verbose);

* this can only be set once, all other calls will be ignored

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 Display for Verbosity

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

Formats the value using the given formatter.

impl FromStr for Verbosity

type Err = String

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this 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.
