Struct FieldMap 

pub struct FieldMap { /* private fields */ }

Ordered multi-map of FIX fields.

Fields are kept in insertion (wire) order. set replaces the first occurrence of a tag in place; push always appends, which is what repeating-group construction requires.

Implementations

impl FieldMap

pub fn new() -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn clear(&mut self)

pub fn contains(&self, tag: Tag) -> bool

pub fn get_raw(&self, tag: Tag) -> Option<&[u8]>

Raw bytes of the first occurrence of tag.

pub fn get<T: FixDecode>(&self, tag: Tag) -> Result<T, ConversionError>

Decode the first occurrence of tag as T.

pub fn get_opt<T: FixDecode>( &self, tag: Tag, ) -> Result<Option<T>, ConversionError>

Decode the first occurrence of tag as T, or None when absent.

pub fn get_string(&self, tag: Tag) -> Result<String, ConversionError>

pub fn get_field<F: Field>(&self) -> Result<F::Value, ConversionError>

pub fn get_field_opt<F: Field>( &self, ) -> Result<Option<F::Value>, ConversionError>

pub fn set_field<F: Field>(&mut self, value: F::Value)

pub fn has_field<F: Field>(&self) -> bool

pub fn set(&mut self, tag: Tag, value: impl FixEncode)

Replace the first occurrence of tag (keeping its position), or append.

pub fn set_raw(&mut self, tag: Tag, value: Vec<u8>)

pub fn push(&mut self, tag: Tag, value: impl FixEncode)

Append a field regardless of whether the tag already exists.

pub fn remove(&mut self, tag: Tag) -> bool

Remove all occurrences of tag. Returns true if anything was removed.

pub fn iter(&self) -> impl Iterator<Item = &TagValue>

pub fn wire_len(&self) -> usize

Total serialized size of these fields: tag=value<SOH> for each.

pub fn write_to(&self, buf: &mut Vec<u8>)

Serialize fields in stored order as tag=value<SOH>.

pub fn read_groups( &self, template: &GroupTemplate, ) -> Result<Vec<FieldMap>, ConversionError>

Read the repeating group counted by template.num_tag.

Group instances are split on template.delimiter(). Any tag that is not in the template’s member set terminates the group section.

pub fn write_groups(&mut self, template: &GroupTemplate, groups: &[FieldMap])

Append repeating-group instances, setting/updating the count field.

Instances must have the delimiter tag as their first field; members are appended verbatim in the order given.

Trait Implementations

impl Clone for FieldMap

fn clone(&self) -> FieldMap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FieldMap

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

Formats the value using the given formatter.

impl Default for FieldMap

fn default() -> FieldMap

Returns the “default value” for a type.
