Struct spidev::Spidev [−][src]
pub struct Spidev { /* fields omitted */ }
Expand description
Provide high-level access to Linux Spidev Driver
Implementations
Open the spidev device with the provided path
Typically, the path will be something like "/dev/spidev0.0"
where the first number if the bus and the second number
is the chip select on that bus for the device being targeted.
Consume the object and get the underlying File
object
Write the provided configuration to this device
Perform a single transfer
Perform multiple transfers in a single system call to the kernel
Chaining together multiple requests like this can reduce latency and be used for conveniently and efficient implementing some protocols without extra round trips back to userspace.
Trait Implementations
Pull some bytes from this source into the specified buffer, returning how many bytes were read. Read more
Like read
, except that it reads into a slice of buffers. Read more
can_vector
)Determines if this Read
er has an efficient read_vectored
implementation. Read more
read_initializer
)Determines if this Read
er can work with buffers of uninitialized
memory. Read more
Read all bytes until EOF in this source, placing them into buf
. Read more
Read all bytes until EOF in this source, appending them to buf
. Read more
Read the exact number of bytes required to fill buf
. Read more
Creates a “by reference” adapter for this instance of Read
. Read more
Creates an adapter which will chain this stream with another. Read more
Write a buffer into this writer, returning how many bytes were written. Read more
Flush this output stream, ensuring that all intermediately buffered contents reach their destination. Read more
can_vector
)Determines if this Write
r has an efficient write_vectored
implementation. Read more
