Struct DefaultRM 

pub struct DefaultRM(/* private fields */);

A ResourceManager which close everything on drop

Implementations

impl DefaultRM

pub fn leak(self) -> WeakRM<'static>

DefaultRM will close everything opened by it on drop. By converting to a WeakRM, such behavior can be avoided.

Note: Sessions opened by another resource manager (get from another call to Self::new) won’t be influenced.

pub fn borrow(&self) -> WeakRM<'_>

DefaultRM will close everything opened by it on drop. By converting to a WeakRM, such behavior can be avoided.

Note: Sessions opened by another resource manager (get from another call to Self::new) won’t be influenced.

pub fn new() -> Result<DefaultRM, Error>

Returns a session to the Default Resource Manager resource.

The first call to this function initializes the VISA system, including the Default Resource Manager resource, and also returns a session to that resource. Subsequent calls to this function return unique sessions to the same Default Resource Manager resource.

When a Resource Manager session is dropped, not only is that session closed, but also all find lists and device sessions (which that Resource Manager session was used to create) are closed.

impl AsResourceManager for DefaultRM

fn find_res_list(&self, expr: &VisaString) -> Result<ResList, Error>

Queries a VISA system to locate the resources associated with a specified interface.

fn find_res(&self, expr: &VisaString) -> Result<VisaString, Error>

Queries a VISA system to locate the resources associated with a specified interface, return the first resource matched

fn parse_res( &self, res: &VisaString, ) -> Result<(AttrIntfType, AttrIntfNum), Error>

Parse a resource string to get the interface information.

fn parse_res_ex( &self, res: &VisaString, ) -> Result<(AttrIntfType, AttrIntfNum, VisaString, VisaString, VisaString), Error>

Parse a resource string to get extended interface information.

fn open( &self, res_name: &VisaString, access_mode: AccessMode, open_timeout: Duration, ) -> Result<Instrument, Error>

Opens a session to the specified resource.

fn close_all(&self)

Close this session and all find lists and device sessions.

impl AsSs for DefaultRM

fn as_ss(&self) -> BorrowedSs<'_>

impl Debug for DefaultRM

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl FromRawSs for DefaultRM

unsafe fn from_raw_ss(s: u64) -> DefaultRM

Safety

impl HasAttribute for DefaultRM

fn get_attr(&self, attr_kind: AttrKind) -> Result<Attribute, Error>

if want a specific attribute, use SpecAttr::get_from

fn set_attr(&self, attr: impl Into<Attribute>) -> Result<(), Error>

impl Hash for DefaultRM

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoRawSs for DefaultRM

fn into_raw_ss(self) -> u64

impl Ord for DefaultRM

fn cmp(&self, other: &DefaultRM) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DefaultRM

fn eq(&self, other: &DefaultRM) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for DefaultRM

fn partial_cmp(&self, other: &DefaultRM) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
