Sebastian Dröge f24b38470b Fix various new clippy warnings

Sebastian Dröge 003554876c Update various APIs to use glib::GStr
Currently only covers what is needed to keep code compiling, plus
everything caps/structure/tags related.

This avoids unnecessary heap allocations for adding the NUL-terminator
of C strings, and especially makes caps/structure handling as efficient
as in C.

Sebastian Dröge fa5491e6b3 Use borrowed miniobject/structure types in more places
When the function does not keep around an additional reference of the
value this is correct and more flexible for callers.

Sebastian Dröge a1165a7456 gstreamer: Add bin/pipeline builders
And also implement the Default trait for them.

Sebastian Dröge 2a4e1069a1 app: Add an AppSrc/AppSink builder
These allows to construct these elements explicitly together with all the
properties instead of going via gst::ElementFactory::make().
2022-10-22 10:19:49 +03:00
Sebastian Dröge 7423b1dea6 elementfactory: Change make() / create() to builders and keep the old variants as create_with_name() / make_with_name()
As a side-effect, this also now includes the element factory name in the
error messages instead of giving the same error string for every
factory.

Partially fixes https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/-/issues/318

Also let them all go through the same, single object construction code.

François Laignel 08551bb1bc format/specific: don't expose inner as pub
... users would be able to bypass the range checks and build a
defined Rust value which would be interpreted as `None` in C code.

Added format module examples for formatted values constructions.

François Laignel 57d8d46ab6 gst/format: fix some ops and add others
Some operations were implemented on types that wouldn't result in
the expected physical unit. E.g.:

- `ClockTime / ClockTime` results in a unit-less factor.
- `u64 / ClockTime` would result in a `1 / ClockTime`. Since we don't
  use any `Frequency` type, this operation is removed. Users should
  use the `ClockTime` accessors to compute the expected value.

This commit also adds:

- multiplications with integers as the left hand side operands.
- `Partial{Eq,Ord} for `Signed<T>` with `T` as left hand side operand.
- `opt_add` / `opt_sub` for `Signed<T>` with `T` as left or right hand
   side operands.
- missing tests for `Partial{Eq,Ord}` and `OptionOrd`.

This implementation can interfere with unrelated code and was removed:

- `Signed<usize>.` `PartialOrd` makes existing code computing the len
  of slices needing type annotation because the len is later used in
  a comparison for which the compiler is unable to determine if
  the len is `Signed<usize>` or `usize`.

François Laignel 986a136492 clock_time & format: basic opt-ops impl

Marijn Suijten f89e840d27 Remove redundant prelude imports
When importing the prelude of a crate like `gst` the `glib` prelude is
provided too.  Shedding these imports saves quite a few lines and
adheres to keeping it simple; we're not reexporting base/parent preludes
for no reason :)
