Struct Message 

#[non_exhaustive]
pub struct Message {
    pub message: Option<String>,
    pub severity: Option<String>,
    /* private fields */
}

Represents a notice or warning message from the database.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

message: Option<String>

The full message string. For PostgreSQL, this is a formatted string that may include severity, code, and the notice/warning message. For MySQL, this contains the warning message.

severity: Option<String>

The severity of the message (e.g., “NOTICE” for PostgreSQL, “WARNING” for MySQL).

Implementations

impl Message

pub fn new() -> Self

pub fn set_message<T>(self, v: T) -> Self

where T: Into<String>,

Sets the value of message.

Example

let x = Message::new().set_message("example");

pub fn set_or_clear_message<T>(self, v: Option<T>) -> Self

where T: Into<String>,

Sets or clears the value of message.

Example

let x = Message::new().set_or_clear_message(Some("example"));
let x = Message::new().set_or_clear_message(None::<String>);

pub fn set_severity<T>(self, v: T) -> Self

where T: Into<String>,

Sets the value of severity.

Example

let x = Message::new().set_severity("example");

pub fn set_or_clear_severity<T>(self, v: Option<T>) -> Self

where T: Into<String>,

Sets or clears the value of severity.

Example

let x = Message::new().set_or_clear_severity(Some("example"));
let x = Message::new().set_or_clear_severity(None::<String>);

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl Default for Message

fn default() -> Message

Returns the “default value” for a type.

impl Message for Message

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Message

fn eq(&self, other: &Message) -> 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.
