Enum BuildError 

pub enum BuildError {
    DirectionNotSet {
        rule_index: usize,
    },
    MissingDestination {
        rule_index: usize,
    },
    InvalidIp {
        rule_index: usize,
        raw: String,
    },
    InvalidCidr {
        rule_index: usize,
        raw: String,
    },
    InvalidDomain {
        rule_index: usize,
        raw: String,
        source: DomainNameError,
    },
    InvalidPortRange {
        rule_index: usize,
        lo: u16,
        hi: u16,
    },
    IngressDoesNotSupportIcmp {
        rule_index: usize,
    },
}

Errors surfaced by NetworkPolicyBuilder::build and the related nested builders (crate::builder::DnsBuilder::build, crate::builder::NetworkBuilder::build).

All these builders accumulate errors lazily — string inputs are stored raw and only parsed at .build() time, where the first failure is returned. The same enum covers both rule-grammar failures (with a rule_index) and DNS-block-list failures (no rule index, since DNS blocks aren’t rules).

Variants

DirectionNotSet

A rule was committed without setting a direction first.

Fields

rule_index: usize

MissingDestination

A rule was committed via .allow() / .deny() but no destination method was called on the resulting RuleDestinationBuilder.

Fields

rule_index: usize

InvalidIp

.ip(&str) received a value that doesn’t parse as an IPv4 or IPv6 address.

Fields

rule_index: usize

raw: String

InvalidCidr

.cidr(&str) received a value that doesn’t parse as a CIDR.

Fields

rule_index: usize

raw: String

InvalidDomain

.domain(&str) or .domain_suffix(&str) received a value that doesn’t parse as a DomainName.

Fields

rule_index: usize

raw: String

source: DomainNameError

InvalidPortRange

.port_range(lo, hi) received lo > hi.

Fields

rule_index: usize

lo: u16

hi: u16

IngressDoesNotSupportIcmp

An ICMP protocol (icmpv4 / icmpv6) appears in a rule whose direction is Ingress or Any. publisher.rs has no inbound ICMP path; ingress ICMP rules would be dead code.

Fields

rule_index: usize

Trait Implementations

impl Clone for BuildError

fn clone(&self) -> BuildError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Error for BuildError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
