pub struct TryIntoHeaderName { /* private fields */ }Expand description
Delayed-fallibility wrapper for conversion to http::header::HeaderName.
buildstructor builders allow doing implicit conversions for convenience,
but only infallible ones.
HeaderName can be converted from various types but the conversions is often fallible,
with TryFrom or TryInto instead of From or Into.
This types splits conversion in two steps:
it implements infallible conversion from various types like &str (that builders can rely on)
and fallible conversion to HeaderName (called later where we can handle errors).
See for example supergraph::Request::builder
which can be used like this:
use apollo_router::services::supergraph;
let request = supergraph::Request::fake_builder()
.header("accept-encoding", "gzip")
// Other parameters

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().

on_green(), which have the same functionality but
are pithier.
§Example

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().

wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};

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:
