Enum DegradationLevel 

#[repr(u8)]
pub enum DegradationLevel {
    Full = 0,
    SimpleBorders = 1,
    NoStyling = 2,
    EssentialOnly = 3,
    Skeleton = 4,
    SkipFrame = 5,
}

Progressive degradation levels for render quality.

Higher levels mean less visual fidelity but faster rendering. The ordering is significant: Full < SimpleBorders < … < SkipFrame.

Variants

Full = 0

All visual features enabled.

SimpleBorders = 1

Unicode box-drawing replaced with ASCII (+–+).

NoStyling = 2

Colors disabled, monochrome output.

EssentialOnly = 3

Skip decorative widgets, essential content only.

Skeleton = 4

Just layout boxes, no content.

SkipFrame = 5

Emergency: skip frame entirely.

Implementations

impl DegradationLevel

pub fn next(self) -> DegradationLevel

Move to the next degradation level.

Returns SkipFrame if already at maximum degradation.

pub fn prev(self) -> DegradationLevel

Move to the previous (better quality) degradation level.

Returns Full if already at minimum degradation.

pub fn is_max(self) -> bool

Check if this is the maximum degradation level.

pub fn is_full(self) -> bool

Check if this is full quality (no degradation).

pub fn as_str(self) -> &'static str

Get a human-readable name for logging.

pub fn level(self) -> u8

Number of levels from Full (0) to this level.

pub fn use_unicode_borders(self) -> bool

Whether to use Unicode box-drawing characters.

Returns false at SimpleBorders and above (use ASCII instead).

pub fn apply_styling(self) -> bool

Whether to apply colors and style attributes to cells.

Returns false at NoStyling and above.

pub fn render_decorative(self) -> bool

Whether to render decorative (non-essential) elements.

Returns false at EssentialOnly and above. Decorative elements include borders, scrollbars, spinners, rules.

pub fn render_content(self) -> bool

Whether to render content text.

Returns false at Skeleton and above.

Trait Implementations

impl Clone for DegradationLevel

fn clone(&self) -> DegradationLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DegradationLevel

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

Formats the value using the given formatter.

impl Default for DegradationLevel

fn default() -> DegradationLevel

Returns the “default value” for a type.

impl Hash for DegradationLevel

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DegradationLevel

fn cmp(&self, other: &DegradationLevel) -> 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 DegradationLevel

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

fn partial_cmp(&self, other: &DegradationLevel) -> 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.
