) -> Result<Self, BoolError>
pub fn with_target<P: IsA<Pad> + IsA<Object>>( self, target: &P ) -> Result<Self, BoolError>
Specifies a target
Pad
for the GhostPad
.
If the PadBuilder
was created from
a PadTemplate
and the PadTemplate
has a specific name_template
,
i.e. if it’s not a wildcard-name containing %u
, %s
or %d
,
the GhostPad
will automatically be named after the name_template
.
If the name_template
is a wildcard-name, then the target
name
is used,
if it is compatible. Otherwise, a specific name must be provided using
PadBuilder::name
or PadBuilder::maybe_name
.

sourcepub fn new(direction: PadDirection) -> Self
pub fn new(direction: PadDirection) -> Self
Creates a PadBuilder
with the specified PadDirection
.
An automatically generated name will be assigned. Use PadBuilder::name
or
PadBuilder::maybe_name
to define a specific name.
sourcepub fn from_static_template(templ: &StaticPadTemplate) -> Self
pub fn from_static_template(templ: &StaticPadTemplate) -> Self
Creates a PadBuilder
from the specified StaticPadTemplate
.
If the StaticPadTemplate
has a specific name_template
,
i.e. if it’s not a wildcard-name containing %u
, %s
or %d
,
the Pad
will automatically be named after the name_template
.
Use PadBuilder::name
or PadBuilder::maybe_name
to specify a different name.
sourcepub fn from_template(templ: &PadTemplate) -> Self
pub fn from_template(templ: &PadTemplate) -> Self
Creates a PadBuilder
from the specified PadTemplate
.
If the PadTemplate
has a specific name_template
,
i.e. if it’s not a wildcard-name containing %u
, %s
or %d
,
the Pad
will automatically be named after the name_template
.
Use PadBuilder::name
or PadBuilder::maybe_name
to specify a different name.
sourcepub fn maybe_name<N: IntoGStr>(self, name: Option<N>) -> Self
pub fn maybe_name<N: IntoGStr>(self, name: Option<N>) -> Self
Optionally sets the name of the Pad.
This method is convenient when the name
is provided as an Option
.
If the name
is None
, this has no effect.

sourcepub fn build(self) -> T
pub fn build(self) -> T
Builds the Pad
.
§Panics
Panics if the Pad
was built from a PadTemplate
with a wildcard-name name_template
(i.e. containing %u
, %s
or %d
)
and no specific name
was provided using PadBuilder::name
or PadBuilder::maybe_name
, or for GhostPad
s,
by defining a target
.
