pub struct JsonPath(/* private fields */);Expand description
A typed path into a JSON document.
Implementations§
Source§impl JsonPath
impl JsonPath
Sourcepub fn concat(&self, tail: &JsonPath) -> Self
pub fn concat(&self, tail: &JsonPath) -> Self
Return self with tail’s segments appended — the FOCUS re-rooting
operation: a divergence found at tail within a focused subtree is
re-rooted at focus.concat(tail) so its report + ratchet signature
name the true location.
Sourcepub fn get<'a>(&self, v: &'a Value) -> Option<&'a Value>
pub fn get<'a>(&self, v: &'a Value) -> Option<&'a Value>
Resolve this path against v, returning the subtree it points at
(or None when any segment is absent / mistyped). A PathSeg::Wildcard
is not resolvable to a single node, so it yields None.
Used by the differ’s FOCUS mode: an Operation
carrying a focus path restricts the object diff to this subtree, so a
field-level invariant (e.g. “a /status PUT left spec.containers[0].image
unchanged”) is compared in isolation from a kind’s unrelated
server-side-defaulting divergence.
Sourcepub fn parse(spec: &str) -> Self
pub fn parse(spec: &str) -> Self
Parse a dotted spec into a typed path. Supports .key, [*]
(wildcard) and [N] (index) segments — e.g.
"metadata.managedFields[*].time" or "spec.clusterIPs".
This is a convenience for authoring mask paths as compact
literals; the result is a fully typed Vec<PathSeg>, not a
string that gets re-parsed downstream.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
