pub struct SelectionSet<'a> { /* private fields */ }Expand description
Represents a selection set in a GraphQL query
A selection set is a group of fields selected together in a query.
Implementations§
Source§impl<'a> SelectionSet<'a>
impl<'a> SelectionSet<'a>
Sourcepub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Whether this selection set is empty. Can only happen for scalars and enums.
Sourcepub fn fields(&self) -> impl ExactSizeIterator<Item = Field<'a>> + 'a
pub fn fields(&self) -> impl ExactSizeIterator<Item = Field<'a>> + 'a
Iterator of the fields of this selection set. For best performance, you should respect the field ordering in the resolver data.
Sourcepub fn fields_ordered_by_parent_entity(
&self,
) -> impl ExactSizeIterator<Item = Field<'a>> + 'a
pub fn fields_ordered_by_parent_entity( &self, ) -> impl ExactSizeIterator<Item = Field<'a>> + 'a
Iterator over the fields in this selection set, ordered by their parent entity. However, how parent entities are ordered (by id, name, etc.) is undefined. For best performance, you should respect the field ordering in the resolver data.
Sourcepub fn requires_typename(&self) -> bool
pub fn requires_typename(&self) -> bool
Whether this selection set requires a __typename field
The Gateway doesn’t need the typename for objects and for various simple cases. But if
multiple type conditions are applied, it’ll be required.

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>

Source§fn bg(&self, value: Color) -> 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>
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);
