Enum OutputFormat 

#[non_exhaustive]
pub enum OutputFormat {
    Pretty,
    Json,
}

The rendering format for an error reported to a consumer.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Pretty

The human-readable Error: {display} line.

Json

The RFC 9457 application/problem+json envelope.

Implementations

impl OutputFormat

pub fn select(explicit: Option<&str>, is_terminal: bool) -> Self

Selects the output format for a consumer.

JSON when --format=json is given explicitly, or when no format is given and the error stream is not a terminal. Pretty when --format=pretty is given, or when no format is given and the error stream is a terminal. An unrecognized explicit value falls back to the TTY heuristic.

Arguments

• explicit - The value of an explicit --format flag, if any.
• is_terminal - Whether the error stream is a TTY.

Returns

The selected OutputFormat.

Trait Implementations

impl Clone for OutputFormat

fn clone(&self) -> OutputFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OutputFormat

impl Debug for OutputFormat

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

Formats the value using the given formatter.

impl Eq for OutputFormat

impl PartialEq for OutputFormat

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