Enum ExplorerWidth 

pub enum ExplorerWidth {
    Percent(u8),
    Columns(u16),
}

Width configuration for the file explorer.

Two forms are supported:

• Percent(n) — relative to the current terminal width. n is a whole-percent value in 0..=100.
• Columns(n) — absolute character columns. n is clamped at render time against the live terminal width so the layout stays inside the window.

Wire formats accepted on deserialize

JSON form	Parsed as
30 (integer)	Percent(30)
0.3 (float in [0, 1])	Percent(30) — legacy fraction
1.5, 30.0 (float outside [0, 1])	Percent(n)
"30%", "30 %" (string with %)	Percent(30)
"24" (string, no %)	Columns(24)

Wire format emitted on serialize

• Percent(n) → string "n%"
• Columns(n) → string "n"

This makes config.json self-describing: the unit is visible on the value, and round-trip is stable.

Variants

Percent(u8)

Columns(u16)

Implementations

impl ExplorerWidth

pub const DEFAULT: Self

Default width when none is configured.

pub const MIN_COLS: u16 = 5

Hard minimum for the rendered explorer width. Configured values smaller than this are accepted (so a hand-edited config round-trips cleanly) but the render path always gives the panel at least this many columns, preventing a 0- or 1-column explorer where the border stacks on itself and the drag-to-resize grip is unreachable.

pub fn to_cols(self, terminal_width: u16) -> u16

Convert to terminal columns.

Percent multiplies terminal_width by the percent; Columns returns the requested count. The result is then clamped to MIN_COLS..=terminal_width so it’s always renderable and always usable. On terminals narrower than MIN_COLS the terminal_width cap wins and we return whatever fits.

Trait Implementations

impl Clone for ExplorerWidth

fn clone(&self) -> ExplorerWidth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExplorerWidth

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

Formats the value using the given formatter.

impl Default for ExplorerWidth

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ExplorerWidth

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for ExplorerWidth

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

Formats the value using the given formatter.

impl FromStr for ExplorerWidth

type Err = ExplorerWidthParseError

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this type.

impl JsonSchema for ExplorerWidth

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn json_schema(_generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

impl PartialEq for ExplorerWidth

fn eq(&self, other: &ExplorerWidth) -> 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 Serialize for ExplorerWidth

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Copy for ExplorerWidth

impl Eq for ExplorerWidth

impl StructuralPartialEq for ExplorerWidth
