pub struct FlushMode(/* private fields */);Expand description
Used in Instrument::visa_flush, specifies the action to be taken with flushing the buffer.
It is possible to combine any of these read flags and write flags for different buffers by ORing the flags. However, combining two flags for the same buffer in the same call to viFlush() is illegal.
Notice that when using formatted I/O operations with a session to a Serial device or Ethernet socket, a flush of the formatted I/O buffers also causes the corresponding I/O communication buffers to be flushed. For example, calling viFlush() with VI_WRITE_BUF also flushes the VI_IO_OUT_BUF.
Although you can explicitly flush the buffers by making a call to viFlush(), the buffers are flushed implicitly under some conditions. These conditions vary for the viPrintf() and viScanf() operations.
Implementations§
Source§impl FlushMode
impl FlushMode
Sourcepub const READ_BUF: Self
pub const READ_BUF: Self
Discard the read buffer contents. If data was present in the read buffer and no END-indicator was present, read from the device until encountering an END indicator (which causes the loss of data). This action resynchronizes the next viScanf() call to read a <TERMINATED RESPONSE MESSAGE>. (Refer to the IEEE 488.2 standard.)
Sourcepub const READ_BUF_DISCARD: Self
pub const READ_BUF_DISCARD: Self
Discard the read buffer contents (does not perform any I/O to the device).
Sourcepub const WRITE_BUF_DISCARD: Self
pub const WRITE_BUF_DISCARD: Self
Discard the write buffer contents (does not perform any I/O to the device).
Sourcepub const IO_IN_BUF: Self
pub const IO_IN_BUF: Self
Discard the low-level I/O receive buffer contents (same as VI_IO_IN_BUF_DISCARD).
Sourcepub const IO_IN_BUF_DISCARD: Self
pub const IO_IN_BUF_DISCARD: Self
Discard the low-level I/O receive buffer contents (does not perform any I/O to the device).
Sourcepub const IO_OUT_BUF: Self
pub const IO_OUT_BUF: Self
Flush the low-level I/O transmit buffer by writing all buffered data to the device.
Sourcepub const IO_OUT_BUF_DISCARD: Self
pub const IO_OUT_BUF_DISCARD: Self
Discard the low-level I/O transmit buffer contents (does not perform any I/O to the device).
Source§impl FlushMode
impl FlushMode
Sourcepub const fn bits(&self) -> ViUInt16
pub const fn bits(&self) -> ViUInt16
Get the underlying bits value.
The returned value is exactly the bits set in this flags value.
Sourcepub const fn from_bits(bits: ViUInt16) -> Option<Self>
pub const fn from_bits(bits: ViUInt16) -> Option<Self>
Convert from a bits value.
This method will return None if any unknown bits are set.
Sourcepub const fn from_bits_truncate(bits: ViUInt16) -> Self
pub const fn from_bits_truncate(bits: ViUInt16) -> Self
Convert from a bits value, unsetting any unknown bits.
Sourcepub const fn from_bits_retain(bits: ViUInt16) -> Self
pub const fn from_bits_retain(bits: ViUInt16) -> Self
Convert from a bits value exactly.
Sourcepub fn from_name(name: &str) -> Option<Self>
pub fn from_name(name: &str) -> Option<Self>
Get a flags value with the bits of a flag with the given name set.
This method will return None if name is empty or doesn’t
correspond to any named flag.
Sourcepub const fn intersects(&self, other: Self) -> bool
pub const fn intersects(&self, other: Self) -> bool
Whether any set bits in a source flags value are also set in a target flags value.
Sourcepub const fn contains(&self, other: Self) -> bool
pub const fn contains(&self, other: Self) -> bool
Whether all set bits in a source flags value are also set in a target flags value.
Sourcepub fn remove(&mut self, other: Self)
pub fn remove(&mut self, other: Self)
The intersection of a source flags value with the complement of a target flags
value (&!).
This method is not equivalent to self & !other when other has unknown bits set.
remove won’t truncate other, but the ! operator will.
Sourcepub fn toggle(&mut self, other: Self)
pub fn toggle(&mut self, other: Self)
The bitwise exclusive-or (^) of the bits in two flags values.
Sourcepub fn set(&mut self, other: Self, value: bool)
pub fn set(&mut self, other: Self, value: bool)
Call insert when value is true or remove when value is false.
Sourcepub const fn intersection(self, other: Self) -> Self
pub const fn intersection(self, other: Self) -> Self
The bitwise and (&) of the bits in two flags values.
Sourcepub const fn union(self, other: Self) -> Self
pub const fn union(self, other: Self) -> Self
The bitwise or (|) of the bits in two flags values.
Sourcepub const fn difference(self, other: Self) -> Self
pub const fn difference(self, other: Self) -> Self
The intersection of a source flags value with the complement of a target flags
value (&!).
This method is not equivalent to self & !other when other has unknown bits set.
difference won’t truncate other, but the ! operator will.
Sourcepub const fn symmetric_difference(self, other: Self) -> Self
pub const fn symmetric_difference(self, other: Self) -> Self
The bitwise exclusive-or (^) of the bits in two flags values.
Sourcepub const fn complement(self) -> Self
pub const fn complement(self) -> Self
The bitwise negation (!) of the bits in a flags value, truncating the result.
Source§impl FlushMode
impl FlushMode
Sourcepub const fn iter(&self) -> Iter<FlushMode>
pub const fn iter(&self) -> Iter<FlushMode>
Yield a set of contained flags values.
Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.
Sourcepub const fn iter_names(&self) -> IterNames<FlushMode>
pub const fn iter_names(&self) -> IterNames<FlushMode>
Yield a set of contained named flags values.
This method is like iter, except only yields bits in contained named flags.
Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
