| Name| Description
| xref:BloombergLP/balst/ObjectFileFormat.adoc[`ObjectFileFormat`] 
| Namespace for object file format traits that select a resolving strategy.
| xref:BloombergLP/balst/ResolverImpl-0f.adoc[`ResolverImpl`] 
| 
| xref:BloombergLP/balst/Resolver_FileHelper.adoc[`Resolver_FileHelper`] 
| This class provides a low‐level file utility functions for `Resolver<Elf>`. This class contains the file descriptor of current object file. Note that the file is opened readonly, and all reads specify the offset, so the offset of the file descriptor is not considered part of the state of this object.
| xref:BloombergLP/balst/StackTrace.adoc[`StackTrace`] 
| This value‐semantic class describes a function‐call stack.
| xref:BloombergLP/balst/StackTraceConfigurationUtil.adoc[`StackTraceConfigurationUtil`] 
| This `struct` provides a namespace for functions that configure the behavior of stack traces performed by `balst`.
| xref:BloombergLP/balst/StackTraceFrame.adoc[`StackTraceFrame`] 
| This simply constrained (value‐semantic) attribute class describes a call frame created on the execution stack when a _parent_ function calls a _child_ function.
| xref:BloombergLP/balst/StackTracePrintUtil.adoc[`StackTracePrintUtil`]

| This `struct` is not intended for use by clients of this component; it exists only for testing purposes.
| xref:BloombergLP/balst/StackTracePrinter.adoc[`StackTracePrinter`] 
| This `class` defines an object that, if streamed to a `bsl::ostream`, will output a stack trace to that stream.
| xref:BloombergLP/balst/StackTraceTestAllocator.adoc[`StackTraceTestAllocator`] 
| This class defines a concrete "test" allocator mechanism that implements the `bdlma::ManagedAllocator` protocol.
| xref:BloombergLP/balst/StackTraceUtil.adoc[`StackTraceUtil`] 
| This `struct` serves as a namespace for a collection of functions that are useful for initializing and printing a stack‐trace object.

| Stream insertion operators
| xref:BloombergLP/balst/operator_eq-00.adoc[`operator==`]
