Enum Level

pub enum Level {
    Debug = 0,
    Info = 1,
    Success = 2,
    Warning = 3,
    Error = 4,
}

The severity level of a FlashMessage.

Levels can be used for filtering and rendering - for example:

• Only show flash messages at info level or above in a production environment, while retaining debug level messages for local development;
• Use different colours, in the UI, to display messages (e.g. red for errors, orange for warnings, etc.).

Variants

Debug = 0

Development-related messages. Often ignored in a production environment.

Info = 1

Informational messages for the user - e.g. “Your last login was two days ago”.

Success = 2

Positive feedback after an action was successful - e.g. “You logged in successfully!”.

Warning = 3

Notifying the user about an action that they must take imminently to prevent an error in the future.

Error = 4

An action was not successful - e.g. “The provided login credentials are invalid”.

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Level

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Level

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Level

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

Formats the value using the given formatter.

impl PartialEq for Level

fn eq(&self, other: &Level) -> 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 Level

fn partial_cmp(&self, other: &Level) -> 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 Serialize for Level

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Level

impl Eq for Level
